Dec 20, 2018 Both large ore particles larger than 0.1mm and small ore particles less than 0.006mm affect flotation efficiency and mineral recovery. In the case of flotation coarse particles, due to the heavyweight, it is not easy to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.
Flotation testwork is carried out using Agitair and Denver cells and is performed by trained, experienced metallurgical technicians to ensure consistent, reliable results. Today froth flotation remains the separation process of choice for most sulphide deposits e.g.

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.
