Mineral Processing and Extractive Metallurgy Review
ABSTRACTHeap leaching is a well-established extractive metallurgical technology enabling the economical processing of various kinds of low-grade ores which could not otherwise be exploited. However despite much progress since it was first applied in recent times the process remains limited by low recoveries and long extraction times.
The dissolution and leaching of minerals: Mechanisms myths
1. Introduction. Leaching is a central unit operation in the hydrometallurgical processing of minerals Crundwell et al. 2011 .Often a leaching stage is one of the initial operations in the process and as a result the efficiency of leaching has a primary effect on the technical and economic success of a hydrometallurgical business.
