Gold Extraction Recovery Processes

Feb 29, 2016  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 process.
