[QUOTE="mbasko, post: 219527, member: 4485"] I see CSIRO have developed a way of replacing cyanide with thiosulphate which is a non toxic chemical. One of the big companies is set to start using it or may have already? [url]http://www.csiro.au/en/Research/MRF/Areas/Mineral-processing/Processing-Australian-ores/Gold-recovery-without-cyanide[/url] They may even be open to assisting a small scale operation set up & trial? Theres also some interesting methods here even though it is to do with removing the use of mercury in small scale/artisan mining. On page 56 on there is a method of crushing, milling & shaker table that gets about 70% of the gold from hard rock. You keep the tailing for later chemical leaching to get the remainder but this could be a method of getting some extraction yourself then possibly having a minimally ran cyanide leaching set up or remove your risk altogether to a processing outfit?
