6/27/2015· Metal value recoveries in extraction are the key issue for sustainability of metals. The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte (a Cu–Fe–S–O melt) and silica-saturated iron silicate slag were determined at 1250–1350 °C, under controlled oxygen and sulfur pressures and at fixed partial pressure of sulfur dioxide, in silica saturation for target ...

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12). Parallel mill circuits increase ...

Complex sulphide ores represent considerable reserves and resources in base non ferrous metals, in precious metals, and in sulphur. Some of their essential characteristics, which allow a general presentation of the complexity of their processing options, from the ore to the pure metals or finished products, have already been presented by the author (1,2).
