Barry Wills& 39; Blog: Flotation & 39;19 Final Report
Flotation using sea water has been intensively studied over the years and two papers from China and Japan looked at the flotation of copper and chalcopyrite-molybdenum separation in sea water. A third paper from Chile described how the bacterium Acidithiobacillus ferrooxidans has shown to be a good depressant of pyrite in seawater flotation.
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz Emirhan M.S. Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid H 2 SO 4 leaching.
Pyrite Depression in Copper Flotation
The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper you need to bring the plant’s pH up to the other side right side of the PYRITE curve. The more flotation collector you have on the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite

Influence of pyrite content on the flotation of chalcopyrite
In the flotation of copper ores several processing plants report that copper recovery is affected by the proportion and type of pyrite in the ore with the effect becoming more intense when the feed ore particles are fine i.e. in fine regrinding. In this work a model mix mineral system consisting of chalcopyrite and pyrite with varying pyrite content in the range 20-80 wt. % was used to
