Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in …

The transformation of iron ore into steel is a remarkable process that involves a series of detailed steps. Beginning with the extraction of iron ore from the earth through mining operations, this raw material is then treated and prepared for the smelting phase. The extracted ore undergoes processes such as crushing, grinding, and …
Mountaintop mining – this mining process is a great option for coal mining, and in this case, the tops of mountains are usually removed and dynamited in order to access the specific coal seams. Once the miners are able to remove the coal, they then cover the disturbed area with topsoil in order to plant trees and grass.
The main raw materials for Steel production in a blast furnace are Iron ore, limestone, coke, and some scrap steel. These materials are charged into the blast furnace from the top and converted into molten pig iron. Next, …
For three-stage crushing, the preliminary stage is frequently a duplication of the first step of the two-stage arrangement shown in Fig. 1, but it is not uncommon for the first machine to be placed near the scene of mining operations if the mine is situated at a considerable distance from the flotation plant.
Explain with a diagram of step-by-step energy conversion in Hydroelectric power plant. Maharashtra State Board SSC (English Medium) 10th Standard ... Explain the stages in electric generation from the given schematic diagram. In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because
The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone …
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called …
