Deep-sea mining has been spurred by the need for critical resources to support growing populations, urbanization, high-tech applications and the development of a green energy economy. Different methods are used for purification for example gravity dependent methods of separation.Over the past decade, deep-sea mining (DSM) has received renewed interest due to scarcity of raw materials. The waste or the impurity of an ore is called gangue. So that separation could be done to get valuable metal or minerals from the impurity or their waste. Mineral processing includes the process of crushing, grinding, and washing an ore. Highwall mining does not involve the coal seam by following overburden removal. Mountaintop removal mining is a method of coal mining that mines coal seams beneath mountaintops by removing the mountaintop overlying the coal seam.ĭredging is the process of mining below the water table. Open-pit mining is the method of extracting rock and minerals from the earth through their removal from borrow. Strip mining includes the mining of seam of minerals by following overburden removal. In surface mining soil and rocks overlying the mineral deposit are removed. The mining used to mine the minerals that are found near to the earth’s surface is surface mining. Ores which are recovered by the process of mining consist of metals, coal, oil and so on. Mining is the process of extraction or removal of minerals from the surface of the Earth generally from an ore body, lode, vein, seam, reef or placer deposit.
Surface mining has different types such as strip mining and open pit mining. The mining which is used to extract the minerals that are found closer to the earth’s surface if surface mining. Hint: The mining is the method of extraction of minerals from the earth generally from ore.
