Insitu Leaching. Describe in details each process? Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Sometimes, hydrometallurgical processes may be carried out directly on the ore material without any pretreatment steps. The mineral extraction process begins with finding the location of mineral deposits. Increasing demand for high grade minerals has compelled miners to carry out more extraction of minerals, which require more energy sources and produce large amount of waste materials. (c) Wastage of upper soil layer and vegetation: Surface mining results in … Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. As crews drill, they mark the exact location and depth of each sample taken. In this process, holes are drilled into the ore deposit by explosive or hydraulic fracturing methods. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size before transportation to the surface. Another way we sample is through trenching, which hugs the surface and is carried out by backhoes or bulldozers. The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. Temperatures were maintained at either 30° (for the mesophilic/thermo-tolerant consortium) or 45 °C (for the two thermo-tolerant consortia), and the reactors were stirred continuously at 150 rpm. The solution purification and concentration processes may include precipitation, distillation, adsorption, and solvent extraction. Heap leaching is carried out in the extraction of copper, nickel, uranium and precious metals. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body. Samples are then sent to an accredited lab, which identifies the type of minerals and grade of gold within them. This is followed by selective flotation to separate bastnaesite and monazite. Remote sensors that use satellite images and geochemical surveys are just two ways that minerals can be located. Insitu leaching is also known as insitu recovery, or solution mining. Many minerals are then removed through mining or quarrying. Tin processing - Tin processing - Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hard-rock mining techniques. Aluminium ore is called bauxite (Al 2 O 3 ). Reverse flotation of iron minerals, an important step in this process, is carried out to produce the final iron concentrate while the cleaner tailings, containing most rare-earth minerals, is processed to obtain a rare-earth concentrate. Aluminium is the most abundant. Q3) [20 Marks] Mineral lube oil production consists of several processes. These processes are usually carried out in the same sequences, Deasphalting Extraction Dewaxing Finishing. metal on Earth, but it is expensive, largely because of the amount of electricity used in the extraction process. The next step is to get the rocks which contain the mineral out of the ground. However, liquid minerals, such as oil or gas, may be extracted by pumping. The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
