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

Biological leaching of a chalcocite ore and its concentrate was studied in both batch and continuous tests in a 3 gL chloride environment. The feed material was obtained from the Zaldivar mine in Chile. The total copper contents of the ore and concentrate were 1.56 and 17.3 respectively and the particle sies were P 108 m and P 53 m respectively. The mineralogy consisted
2019-9-17The ground IP survey tested identified copper-cobalt-silver soil anomalies for geophysical characteristics typical of concealed copper-cobalt-gold sulphide bodies. These large surface geochemical anomalies are believed to represent alteration ones associated with buried intrusive-related copper-sulphide systems within the Mt Gilmore trend
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

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
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
