Open Pit Mineral Processing Ste By Step
What is the process of open pit mining?
Open-pit mining is a method that involves the extraction of minerals from the Earth by excavation, leaving an open pit. Its process is generally divided into the following steps: Exploration for mineral deposits. Planning for excavation. Stripping of the overlying soil. Excavation of ore and mineral. Ore/mineral processing. Land reclamation
