CLS will leach pieces of gold 40 mesh and smaller within 8 to 12 hours This is a definite advantage over cyanide which can take up to a week to leach 40 mesh gold This presents a number of trade offs between CLS and cyanide In most cases the CLS leaching system can be built much smaller than the cyanide systemNov 08 32 cyanide usage for gold leaching greeting all first off let me say that yes i fully realize and accept how dangerous cyanide is but as it can improve the expedience of the gold refining process i figured it was at least worth looking into ive been researching ways to extract and refine gold from computer parts
