Sulphuric acid is employed occasionally as a modifying reagent, but its use is steadily decreasing, being confined chiefly to the treatment of lead and zinc ores. There are, however, one or two ores containing sulphide copper minerals which need an acid circuit for successful flotation.
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 …
