In the process of FIG. 1, for example, in which it is intended to leach nickel preferentially with respect to copper and PM's in a nickel-copper matte, FIG. 4 illustrates clearly the relationship between redox potential and leach selectivity for chlorine leaching of a particular nickel-copper matte.

The INCO Ltd. Copper Refinery Electrowinning Department (CRED) in Copper Cliff, Ontario, processes a Cu, Ni, Co, Fe, As, S and precious metals containing residue produced by the INCO Pressure Carbonyl (IPC) plant. This residue is treated batchwise in two successive leaching stages. The non-oxidative First-Stage Leach (FSL) process extracts the vast majority of the Ni, Co, Fe and As values. The ...

Iron and cobalt sulphates contaminate the nickel sulphate stream due to dissolution during the matte leach process. While iron is an unwanted contaminant, cobalt sulphate production presents a potentially valuable by-product, as long as removal of these metal ions does not introduce other forms of contamination into the solution. Experimental ...

2020-2-13 The process is applicable to a wide range of zinc sulphide concentrates ranging from high grade marmatitic or sphaleritic material to complex zinc-lead bulk concentrates. The process is readily integrated with existing roast-leach plants or it can entirely replace roasting in a new plant, in which case a two stage version of the process is used.
