calcium feldspar yield Evaluation and application in different industries

In this article, we want to analyze the calcium feldspar yield evaluation and also define the application of feldspars in different industries.

In this study, physical and physicochemical tests were performed to improve the quality of feldspar ore collected from the Sidiayti massif located in the Gapsa region of southwestern Tunisia. After determining the mineralogical and chemical composition, the flotation method was used. In this study, the flotation method without hydrofluoric acid for the separation of feldspar and quartz was compared with the existing HF/amine method. As a result, it was found that the existing HF/amine method is the most efficient and selective method.

Experimental studies have shown that these stones produce concentrate suitable for industrial use. Feldspar efficiency was used to evaluate the efficiency of the process. In addition, cone shrinkage, water absorption, solidification degree, mechanical properties (flexural strength) and dielectric behavior were used to monitor the quality of recycled feldspar.

Introduction

Demand for feldspar, a raw material for the ceramic and glass industries, continues to grow. There are no traditional ore sources in Tunisia for flash feldspar, pegmatite and nepheline. This means that a significant part of this raw material was imported (26 million dinars in 2016). This has created the need to explore other types of sediments, such as arcotic sandstone. In southern and central Tunisia, there are extensive deposits of Arcotic sandstone (Sidi Aïch Formation). This formation contains two major industrial minerals: potassium feldspar (microcrystal) and quartz.

Many articles have been published on the use of collectors for feldspar flotation. Feldspar has traditionally been separated from quartz using an amine-type cation collector and hydrofluoric acid as a feldspar activator.

Clear to translucent, colorless to white opal is similar in appearance to moonstone, but lacks the luster of maturity. The refractive index and specific gravity are much lower than those of similar moonstone properties. Even in cross-polaroid polarizing positions, opal remains dark.

The discoloration of labradorite is very obvious and should not be confused with the lower non-opal gemstones. Naturally, agate has a much lower refractive index. and SG. As I said before.

Amazonite can be mistaken for jade, but has a distinct reticulated surface appearance and R.I. and SG. It is enough to separate these two substances. Chrysoprase is not the same as amazonite. There is no reticulation and the cracks are not shiny amazonite cracks, but oyster-like cracks with a waxy sheen. A liquid with a specific gravity of 2.57 helps separate materials such as amazonite.

Aventurine quartz may look like amazonite, but it is exactly R.I. You can tell by measuring.

Moonstone looks a lot like glass or plastic, but this material is distinctive because it has no or one crack. Goldstone is a glass made of copper crystals. This stone is somewhat similar to sunstone, but contains recognizable bubbles and copper octahedrons.
