Ore is natural rock that contains valuable minerals, typically metals and is extracted from the earth through mining and extracting the valuable metals or minerals. The grade of ore refers to the concentration of the valuable material it contains. Subsurface mining involves digging tunnels or shafts into the earth to reach buried ore deposits.

This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained from the ore and allowing mining companies to increase the overall profitability of a mine. The beneficiation process can be performed in a number of ways according to the requirement.

1) Open-Pit Mining: Open-pit mining is the most common method used for nickel mining, especially for large, near-surface deposits. It involves the excavation of the ore body using heavy equipment and machinery, such as excavators, haul trucks, and drills. Open-pit mining is suitable for deposits that are spread over a wide area and are not …

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
b. Underground Mining: Underground mining is employed when the iron ore deposit is located at significant depths. It involves creating underground tunnels and shafts to access the ore. Specialized mining equipment, such as drills, loaders, and haulage vehicles, is used to extract the ore from underground.
