Open Pit Mining Techniques

Open-pit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic. When this occurs, the exhausted mines are at times converted to landfills for disposal of solid wastes. Get price

Cut

A cut-off grade (COG) is an industry-accepted standard expression used to determine what part of a mineral deposit to include in a mineral resource estimate (MRE). For MRE reporting, COGs tend to be rounded down to ensure that material of no economic significance is excluded from the resource. Get price

In gold mining, two main processes, one based on mercury and the other based on cyanide, are used to aggregate gold dust after its segregation from the placer deposit or from the ore‐bearing rock. These processes are very toxic to the artisanal community and to the environment, in particular, to rivers where all the chemical waste is dumped (e.g. Amazon River). Get price
