Improve resource utilisation by lowering cut-off grade: Due to upgrading of the plant feed by preconcentration, the cut-off grade can be lowered and mining reserves increased. In greenfield projects, the size of downstream processing equipment may be reduced (reducing the capital and operating costs) or the production rate may be increased.Open pit copper mining - MAXAMOpen-pit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts.
