English Task 4 - Answer

1. When we have seen our audience, the next step is to adjust the presentation style or model to our audience, for example when we present in front of high school students, then we can present casually and then when we present in front of our superiors it would be nice to be serious.

2. Structure is a kind of summary of ideas from our presentation ideas, so that the audience can understand the meaning of our ideas well and are easy to remember.

3. I strongly agree to do repetition in presentations because repetition makes the audience understand more and our presentation ideas can be remembered easily and the presentation can run systematically.

4. Being authentic is that we have to strive to be ourselves, because when we convey ideas using someone else's style, it feels different and you will feel uncomfortable with your delivery style.

5. I will start practicing before starting the presentation, at least 30 minutes to 1 hour of practice, so that we can get more confidence when giving a presentation.

English Task 2 - Answer

1. First, the copper ore is taken from the site and then transported using a dump truck to the processing facility, then the ore is fed into two types of crusher for crushing, namely the primary crusher, then the second is called the gyratory crusher. Furthermore, after the crushing phase, is the grinding phase, this phase uses water in a device called the sag mill and ball mill, which are used to separate impurity minerals. To increase the degree of flotation of copper, usually after the grinding phase, the ore is inserted into a device called a pneumatic flotation cell so that the copper ore can stick and produce copper that is suitable for sale on the market, then it will enter the tailling stage, which is separation and removal of minerals that are useless or usually called the mineral disturbance in a tool called thickenen tailings. Furthermore, for copper packaging each is placed in a big bag, each with a big bag capacity containing 2 tons of copper with a concentration of 20 to 28 percent. then copper can be marketed or it can be smelted and then marketed

2.- The main part of the Jaw crusher is two steel plate ones can open and close like a jaw. The ore entering the crushed cavity will immediately receive a compressive force or compression from being moved. Crushed ore will down until it gets new pressure. The ore crushed freely will freely fall between the two compression. In the jaw crusher, ore crushing only occurs by the tool, namely when the jaw moves to exert pressure

-Gyratory crusher is used when necessary tools capable of producing large capacity products. Operation or the crushing mechanism by Gyratory crusher is full time crushing. This means that this tool crushes the ore during spin cycle. So this tool is much more efficient than with a jaw crusher. There is, however, a gyratory crusher entail capital costs and maintenance costs big.

-Ball Mill, using a ball-shaped grinding media made of steel. The diameter of the grinding media varies from 25 to 150 centimeters. The mill length, L and the diameter, D, are relatively the same, L = D. Based on the way the product is discharged, or discharge, the ball mill is divided into Overflow mill and grate discharge mill.

-Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

-Pneumatic flotation has been successfully applied for sulphide and oxide copper minerals, copper slag, iron ores (reverse flotation) and gold, and also appears promising for molybdenum concentrates. Difficult separating conditions have been encountered in various process stages, including roughing, cleaning and scavenging. Pneumatic flotation can essentially be applied in any separation where differences exist between mineral and gangue interactions with water. Even high relative density slurries can be processed because the range of amenable particle sizes is quite broad, and the number of cleaning stages required has not exceeded one in our experience

-Thickeners are recognized as one of the more cost-effective technologies for recovering water from tailings streams. Significant energy savings can be achieved by maximizing the recovery of water close to the mill. In addition, a higher density of tailings deposited in the dam tends to reduce the footprint and produce a more stable tailings deposit. When considering a thickened tailings solution, there is the question of whether the technology to thicken tailings should be located in the thickener as a piece of equipment, or whether a complete solution is required to achieve the best performance.

English Task - Answer

Consentrate is valuable minerals that are separated from the ore after undergoing certain processing.

In order to effectively mine/gather various minerals (elements) it’s very important that they are concentrated. We know there is gold in every gallon of sea water, but it’s so little that it’s not possible to extract gold from water and make it profitable. On the other hand during the goldrush people could find many oz of gold in rivers and make a good coin (keep in mind only a very small fraction actually made enough gold though). This is just as true with Iron, Silicon, Aluminium, Uranium and rare earth metals.

An important process is the process of magma movement to determine where the minerals are concentrated or what we can call the volcanic magmatic environment which has several phases and stages of mineral formation.

Tin,nickel, and copper

because

Indonesia has one of the largest tin reserves in the world, and tin itself is very functional for this modern era

Indonesia copper has a very vital function and can also boost the economy of the nation because of its very large reserves

because nickel is a high-class mineral that has a good price to boost the wheels of the Indonesian economy

The material that I like most of the clothes is cotton

Cotton cloth is a fabric obtained from the fine fibers that cover the seeds of the cotton plant. Cotton fibers in the next stage can be processed by being spun into cotton threads before they are woven into cotton sheets.

Cotton fiber is a very valuable basic material, because in the production process it only leaves about 10% of the gross weight. Furthermore, in the processing of cotton fabrics, cotton fibers must be cleaned of fatty, wax and protein elements, so that pure cotton or natural cellulose polymers can be obtained. 

The unique structure of natural cellulose, gives it a special advantage as the main ingredient of cotton fabrics. its characteristic is that it can absorb sweat, is strong and durable, so that it becomes a fabric that is in great demand by many people
