Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Guides For High-sulfide Gold Processing

According to the nature of the ore and the gold processing test results, the coarse grinding-mixed flotation-regrinding- sulfide separation processes can better recover gold. Choosing the right grinding fineness can help avoid over-grinding, which is the first prerequisite for reducing grinding costs and improving recovery.
