Limestone is found near the surface (called a surficial deposit); hence, it is produced mainly from surface mines.By and large, limestone is mined by two methods: opencast stripping for hilly deposits and open-pit mining for plain deposits. To meet the industrial requirements of a large country like India, medium- and small-sized mines of …

The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account ...

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
