It is really really really really really interesting to read these old chemistry guides with a knowledge of geology. By functionally ignoring the words and focusing on the reactions that are happening, you can piece together the real minerals despite the translators' struggles for the right word.
Tumblr media
Like here, "Zungufr" is clearly "red ????". The translators (there were two translations before this one) likely didn't have a knowledge of mineralogy. From the rest of the text, I'm fairly certain Copper acetate is either Copper Acetate or Copper Nitrate, to be added with (NH)4Cl and Malachite (Hydrated Copper Carbonate). However, the end result via the translator is Cinnabar - which is a theoretically reasonable guess. Natural cinnabar is red, and so is arsenic sulfide. However, there's literally no As or Hg in this equation, which means that the result is the red Copper Oxide mineral, CuO. Cuprite.
Tumblr media
Likewise, you have "The Calcination of Lapis Lazuli", which I thought was interesting in the first place, because in the beginning of the text, Al-Razi describes all the reagents. (21) The translator decided to stick with Lapis Lazuli, although seemingly aware that Azurite and Lapis Lazuli are not even close to the same mineral.
Tumblr media Tumblr media Tumblr media
However, when you look at the minerals in 21, something doesn't add up. I was already suspicious of the Lapis Lazuli description, but something was clearly wrong in 21. Neither Lapis nor Hematite have copper, or are "oily/vitreous" minerals. Plus, they already described "Iron Oxides" above this point. Which makes it much more likely that "Lapis Lazuli" actually means Azurite, and Hematite is actually describing Sphalerite, (Zn,Fe)S, and Al-Razi prefers the Fe-rich Sphalerite.
This was also supported by his description of several "zinc ore" minerals, but I couldn't find a good description of sphalerite among them. Then I realized that what Al-Razi was really describing were different variations of Zinc Oxides, and separating out Zinc Sulfides.
Tumblr media
Talc does NOT glitter. And there's no reason to differentiate "sea-talc" and "mountain-talc". But there would be if you knew there were Fe-Micas and Mg-Micas! (Or even just the straight Al-Mica.)
But to be clear, this is not the fault of the translators!! The fact they got close enough I can recognize the errors and described the mineral well enough I can recognize these reactions are a blessing in and of itself.

What Are the Benefits of Diatomaceous Earth?
Introduction 
Diatomaceous Earth, or Diatomite or Kieselguhr in German, is a chalky sedimentary rock made from the skeletal material of aquatic plants called Diatoms. Each particle has a structure that resembles a snowflake, rods and cones, and a honeycomb. It also has holes in it. When examined under a microscope, the particles resemble broken glass when they are crushed into a fine powder. Because of its extensive industrial knowledge, Seema Minerals & Metals offers natural and calcined diatomaceous earth, diatomite, and kieselguhr powder at the best prices. It is also one of the diatomite manufacturers in India. Due to its structure and properties, it is utilized extensively in industries, agriculture, and animal feed.
Uses of Diatomaceous earth:
There are numerous applications for diatomaceous earth. Diatomaceous Earth is used to make calcium silicate boards, fireproof safes and cabinets, brake liners, mold release in latex products, mold release in auto parts spun pipes, mold release in animal feeds as a carrier and directly used, aquaculture, coil coating paints, oil well drilling, in an oil refinery, as an anti-caking agent in fertilizers and animal feed, for grain storage, paper manufacturing, filtration of edible oil, pharmaceutical drugs, chemicals, and as a catalyst in the We process
Agriculture
In the nursery, DE can be used to control various bugs and irritations. It can be utilized, for instance, to eradicate slugs and snails from vegetable gardens. Additionally, mites, aphids, and whiteflies, which can harm plants, are eliminated by diatomaceous earth. If you're looking for Calcined Diatomaceous Earth in India, Diatomite Kieselguhr Manufacturers in India, and diatomite manufacturers, Seema Mineral is the company to deal with. The protective coating of DE Silicon Fertilizer Granules shields the surface from chemicals, gasoline, wind, water, and other elements. As a result, paint and other products that are subjected to chemical reactions and weathering can be used as coating materials.
Benefits of diatomaceous earth
Diatomaceous earth has been adapted to almost all industrial filtration applications, including the processing of oils, alcoholic and non-alcoholic beverages, antibiotics, solvents, and chemicals. In the past, it was primarily used as a filter to clarify sugar and syrups. A second major application is as a filler or extender in numerous products, including paper, paint, brick, tile, ceramics, linoleum, plastic, soap, and detergent.
Conclusions
The fossilized remains of diatoms, which are small aquatic organisms, are what make up diatomaceous earth. Natural silica is the material used to construct their skeletons. Diatoms accumulated in the sediment of rivers, streams, lakes, and oceans for a considerable amount of time. These areas are used to extract silica deposits at the moment. Silica is very common in nature and accounts for 26% of the weight of the earth's crust. Sand, emerald, quartz, feldspar, mica, clay, asbestos, and glass are all examples of various forms of silica. Silicon, a silica component, does not naturally exist in its pure form. Silicon dioxide is typically produced when it reacts with oxygen and water. On the other hand, it might contain very little crystalline silicon dioxide.

What’s the difference between Bone China and porcelain?
What’s the difference between Bone China and porcelain?
Chapter one-The Raw Material
Because Bone China is a kind of porcelain, the raw materials used are almost similar.With one key difference—Bone China actually contains real bones (cow bone ash, usually). This special ingredient makes Bone China thinner and smoother than regular porcelain, giving it a creamy, white color and opaqueness.
Clay: The specific composition of clay is typically determined by where it is extracted. Regardless of where it is obtained, clay will frequently have very similar characteristics. All clays, for example, vitrify only at high temperatures. The sole exception is when the addition of certain materials reduces the vitrification threshold. Furthermore, burned clays have a refractory contribution to the completed product.
Feldspar: Feldspar is primarily made up of flint and aluminum silicate. Flint is hard quartz that is used as a flux in a porcelain composition. Changes can be utilized to lower the temperature at which liquid glass is produced, typically around 1000 to 1300oC.
Silica: Silica is a chemical molecule produced by the interaction of silicon and oxygen gas, two of the most common elements on the planet. It occurs naturally in three forms: amorphous, crystalline, and impure, as seen in quartz, sand, and opal, respectively.
China stone: China stone is a partly kaolinized, feldspar-rich type of granite that contains no iron and is used in the manufacturing of bone China (see later). Its mineral makeup includes mica, quartz, and feldspar, and it is frequently found in conjunction with kaolin. The resemblance of China stone to Petuntse, which is used to produce hard-paste porcelain, is likely why it became a significant component of bone China.
Kaolin: Kaolin is a clay mineral that is white and produced by the weathering of other aluminosilicate minerals. It is utilized in the majority of contemporary ceramics.
Bone ash: Bone ash is calcined, crushed, and finely powdered animal bones used in Bone China production. Typical bone ash comprises roughly 56% calcium oxide, 42% phosphorus pentoxide, and the remainder water. The calcination process takes place at a temperature of about 1,000 °C.

Classical Vajikarana formulation Review
Tumblr media
Vajikarana (aphrodisiac therapy) mainly deals with the promotion of sexual health, healthy progeny, and treatment of male sexual disorders such as premature ejaculation, erectile dysfunction, and infertility. The formulations described in Ayurveda generally contain ingredients of herbal, herbo-mineral, metal, or animal in origin.
Musali or Shweta (White) Musali is a potent herbal drug primarily utilized for Vajikaran therapy and indicated in the management of male infertility. Until date, no published information is presented in compiled form on the classical formulations of Musali with their dose and indications. Therefore, in this study, an attempt has been made to compile different formulations of Musali indicated for Vajikarana therapy.
so here is the classical review on vajikaran. go to Maxx Ayurveda website for more information and find solution about your sexual problems.
This study aims to gather information on various formulations of Musali primarily utilized for Vajikarana therapy. Critical review of various formulations of Shweta Musali is compiled from seven Ayurvedic texts, and the therapeutic efficacy of Musali is discussed on the basis of available data. Vajikarana formulations of Musali were discovered after Samhita period. In the present review, 51 formulations of Shweta Musali are found, which are mainly indicated for Vajikarana. In the formulations of Musali, ingredients such as Godugdha (cow’s milk), Goghrita (cows clarified butter), Khanda sharkara (sugar), Madhu (honey), Ashwagandha (Withania somnifera L.), Shatavari (Asperagus racemosus Wild.), Vidarikanda (Pueraria tuberosa), Abhrak, Bhasma (calcined mica), and Rasasindoor (red oxide of mercury) augment the Vajikarana potential of Musali and also help to prevent other complications.

kaolin processing plant Processing line for kaolin
Introduction of main processing technology of kaolin: Kaolin processing technology generally includes beneficiation purification, ultra-fine crushing, calcination and surface modification. The original kaolin ore contains kaolinite minerals as the main components, and there are small amounts of montmorillonite, illite, diaspore, quartz, feldspar, mica and iron minerals (limonite, hematite, diamond) Iron ore, pyrite, etc.), titanium oxides (ilmenite, rutile, etc.), organic matter (plant fiber, organic peat, coal) and other impurities. As a mineral filler application, it must be beneficiated and purified. The processing technology of kaolin depends on the type of ore. Different beneficiation and purification processes are adopted for soft kaolin, sandy kaolin and hard kaolin (kaolinite). Dry and wet separation are the two main processes of the kaolin beneficiation process. The dry separation process is used to process kaolin ore with high whiteness and low grit content. It is easy to operate and saves costs. The raw kaolin ore is crushed in a crusher, and then the kaolin concentrate can be obtained by grinding in a Raymond mill. Wet kaolin beneficiation process is used to process complex kaolin ore. Wet beneficiation process uses high gradient magnetic separation, foam flotation and selective flocculant to make full use of kaolin mineral resources.     Main production process of kaolin: 1.pounding The raw ore is added with water and dispersant according to the set concentration requirements, and is made into pulp in a mixer or a tamping machine. The purpose of pulping is to disperse kaolin and separate it from sandy minerals and plant impurities in order to prepare a slurry of suitable concentration for the next process. 2. Spiral classifier to remove coarse sand The raw particles of kaolin clay such as quartz, feldspar, mica and other impurities have coarser particle sizes, generally larger than 325 mesh, while the particles of kaolin have finer particle sizes, mainly concentrated in -2μm. A spiral classifier can remove most of the quartz and feldspar coarse sand. 3. Sorting of hydrocyclone The hydrocyclone is used for separation. The operation is to remove kaolin fine sand (fine-grained quartz, feldspar and other impurities). Generally, hydrocyclones with different diameters such as Ø75, Ø50, and Ø25 are used for multiple sorting. 4. Classification of horizontal spiral centrifuge The horizontal spiral centrifuge is used for classification, and the process parameters (such as separation factor) can be adjusted according to different materials to keep the product quality stable. At present, domestic kaolin beneficiation also adopts hydrocyclone for selective classification, but due to the influence of flow and pressure changes, the product quality is difficult to stabilize at -2μm accounting for more than 90%, and the classification efficiency is not as good as horizontal spiral centrifugal classifiers. 5. Magnetic separation In order to obtain high-quality or high-quality kaolin, in most cases, strong magnetic separation or high gradient magnetic separation, chemical bleaching, even flotation and selective flocculation are required. The dyed mineral impurities in kaolin, such as limonite, hematite, siderite, pyrite, anatase, rutile, etc., have weak magnetic properties, so the kaolinite after sand removal can be further used strong magnetic separator or high gradient The magnetic separator performs magnetic separation. Since most of the iron and titanium minerals in kaolin are embedded with finer particle size, the removal rate of strong magnetic separation is generally not high. Therefore, most of the industries currently use high gradient magnetic separators for magnetic separation of kaolin. In addition, superconducting magnetic separators with better performance have also been used for the magnetic separation and iron removal of kaolin. This magnetic separator not only further improves the strength of the magnetic field, but also obtains high-quality high-quality kaolin and reduces energy consumption. If the whiteness index of kaolin after magnetic separation still cannot meet the requirements of high-quality kaolin, chemical bleaching is generally adopted. The special magnetic separator for washing kaolin is a wet strong magnetic separator. The magnetic strength is up to 16000GS. It can remove the regenerated iron in the kaolin during the kaolin grinding process to improve the whiteness. And other weak magnetic substances. 6. Chemical bleaching The chemical bleaching of kaolin is often related to the use performance of kaolin and the impurities contained. The main impurities affecting the use performance of kaolin are iron minerals, titanium minerals and organic matter. Commonly used chemical bleaching includes reduction method, oxidation method, oxidation-reduction combined bleaching method, acid leaching treatment method, etc. 7. Pressure filter process Using high-pressure slurry feeding to improve productivity, ensure product moisture is less than 32 to 35%, save energy consumption and improve working environment. 8. Drying process Powerful drying can be used.   Kaolin powder specifications: The specifications of kaolin powder include 100 mesh, 200 mesh, 325 mesh, 800 mesh, 1200 mesh, 2000 mesh, 2500 mesh, 3000 mesh, etc. What kind of equipment is needed to process kaolin ore? It is mainly to determine the finished product according to the use The fineness range belongs to coarse crushing or fine crushing. The equipment used for coarse crushing between 50~325mm is Raymond grinding equipment or ultrafine ring roller mill. The fine crushing is divided into 325~2500 mesh. The equipment is micro-powder grinding equipment such as kaolin powder ultra-fine vertical mill, which can determine which production line is used according to the fineness of the finished product. Regardless of the coarse crushing production line or fine crushing production line, the entire production line includes the crusher and the milling process. For the powder processing of attapulgite, it can be used directly because of its small size. Read the full article

China Clay Market to See Incredible Growth During 2025
China clay, also known as kaolin, is a loose, dense, fine, flaky, earthy aggregate mineral in white color found in the earth’s crust. Kaolin is the name derived from its raw material called kaolinite, a clay mineral. Presence of impurities affects the color of china clay, which becomes reddish, brownish or bluish. This impacts the commercial value of the product. Its commercial utility is influenced by its properties that include purity, brightness, glossiness, viscosity, and abrasiveness. China clay is available in the form of deposits formed by chemical weathering of aluminum silicate minerals such as feldspar through a complex sequence of events. China clay deposits are classified into primary and secondary deposits. Primary china clay originates from weathering of rocks containing high concentrations of feldspathic minerals and is found in the place where the deposition occurs. Secondary china clay is subsequently settled in another place by being carried along by water currents with other minerals such as quartz and mica.

1. Application status of kaolin
Naturally produced kaolin ores can be classified into three types: hard (coal) kaolin, soft kaolin and sandy kaolin according to their quality (physical and chemical properties), plasticity and sand content (quartz, feldspar, mica and other mineral particle size >50 micron). In general, domestic kaolin (kaolinite) is more suitable for the development of calcined kaolin, mainly used in all kinds of filler. Calcined kaolin is also used in papermaking because of its high whiteness, and it is more expensive to produce high grade copper plate. But the calcined soil mainly used to increases the whiteness, it is generally not used alone, and the amount of the soil in the paper is less than that of the water washing soil.
