Open Cast Mining Of Copper Ore
Open Pit Mine
Open Pit Mine. Open-pit mining refers to a mining method where ore and waste rocks are removed separately from the surface of a mineral deposit. It is a cost-effective option for deposits that are wide and close to the surface, allowing for efficient extraction of minerals and better control over operations.
