Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.
processing of low grade gold ores by heap leaching is an important technological development. But a major drawback in heap leaching process is low recovery of the precious metals. The problems that generally lead to a low gold recovery and the possible solutions are discussed. INTRODUCTION Low grade gold deposits once considered uneconomic are ...
After gold content is increased by physical and mechanical methods the concentrate is used as feeding material for next steps. Gold concentrates are processed by chemical methods in order torecover up to > 99% gold, depending on type and efficiency of the processes [14]. The widely used chemical treatment process is the leaching with cyanide.

Ore that contains free gold and/ or silver may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large metal particles. Such ore may first be subject to a gravity recovery process to recover the free gold and /or silver before being subjected to cyanide leaching.
A PROCESS FOR COPPER AND/OR PRECIOUS METAL RECOVERY . ... or by using another gold recovery process (eg, cyanidation). Copper selective leaching will reduce the gold losses due to a cementation mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the preleaching stage. ... In a third aspect, there ...
High Recovery Rate Gold Carbon In Leach Plant /gold Ore . At present, the dressing methods are mercury mixing gold leaching process and cyanidation gold leaching process. Mercury mixing gold leaching process is a kind of ancient gold process, which is simple and convenient and economical.
the process design of gold leaching and carboninpulp saimm. the south african underground gold mining industry small changes in recovery and efficiency have a significant value over the life of the project this paper describes the process issues that should be considered during the design of leach and cip/cil circuits in order to ensure that these objectives are met in addition
