Copper Hydromet Gaining Ground for Sulphide Ores.. COPPER HYDROMET GAINING GROUND FOR SULPHIDE ORES Hydrometallurgical processes for treating copper sulphide ore and concentrates are gaining ground with significant
1. Introduction. Low grade dumped ores of copper have always been a serious concern for the copper ore processing industries. On one hand the conventional methods of metal extraction have been unsuitable in extracting the metal values economically while on the other dumping of such ores results in serious environmental concerns

The invention provides processes that significantly reduce acid consumption while maintaining efficient leach recovery of copper from oxide and acid consuming ores. The invention provides a hydrometallurgical process that reduces acid required for leaching in the presence of a solid ion exchange media. The presence of the ion exchanger leads to copper extraction from solution into the

2012-4-11A recent example is the novel process proposed for the cotreatment of nickel sulphide and laterite ores that may occur in close proximity Liu et al. 2006. In this process the leaching of a nickel laterite ore generates a pregnant leach solution containing more than 1030 gL FeIII that is used for the leaching nickel sulphide ore either sequentially or simultaneously

A large proportion of the environmental impacts of a technology is determined by decisions made at the early development stages. Therefore effective approaches to grasp the potential environmental performance of a technology early in development are needed. This paper reflects on the usefulness of ex ante application of LCA using a case study on the appraisal of the potential environmental
Similarly the results of several studies on dump and heap leach copper ores from Chile and the US showed that HPGR comminution resulted in an increase in copper extraction when compared to the conventionally crushed ore Apling and Bwalya 1997 Daniel 2007 Klymowsky et al. 2002
