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
