viable to process mineral resources very much depends on the type of ore which is mined as well as of the physical conditions linked to the location of the mine site Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions.

Artisanal and Small Scale Gold Mining Without Mercury

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost The best practices for chemical leaching are a combination of pre concentration and mill leaching as they lead to the least amount of waste a short processing time for miners and high gold recoveries.
