This research aims to explore possible solutions to the problems presented in auriferous sulfide minerals , which have cianicidas by metals ( Gold companions ) can not be cyanide by high reagent consumption , which makes the process uneconomical . Also be a problem hitting the small domestic mining sites that have these features that can not be traded concentrates by high penalties imposed on them , then creating a social problem that should be taken into account. At the experimental level by testing and subsequent acid leach cyanidation seek to find a process that allows for adequate separation of gold copper and other species also have high technical and economic efficiency.
