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
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
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

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

2019-10-1Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper
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
