In this work, different flotationpreoxidationcyanidation methods are considered for treating a low-grade refractory gold ore.On the one hand, the results of selective flotation show that 22 and 31.1 of total sb and as, respectively, remained in the final tailings and only about 28 of the total au remained for further cyanidation processes.
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.
