One way to improve gold recovery by flotation is to consider the use of nitrogen as flotation gas. There is a process developed by Newmont Technologies and it is called N 2 Tec®. The use of nitrogen inhibits the oxidation of auriferous sulfide mineral fines and measuring pulp potential would appear to be a useful method of monitoring the ...

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 …

This study aimed to investigate the applicability of coal-oil gold agglomeration (CGA) assisted flotation to recover gold from a refractory ore. The ore with the grade of 2-5 g/t was tested with the CGA-flotation process in six different size fractions from 38 to 300 urn using different collector types and dosages. In addition, the flotation without CGA was performed …
