CHAPTER 7 FLOTATION OF SULPHIDE MINERALS
Flotation of Chalcocite Cu 2 S Chalcocite Cu 2 S and chalcopyrite CuFeS 2 are the two most commonly floated copper sulphide minerals. Bornite Cu 5 FeS 4 and covellite CuS and energite Cu 3 AsS 4 are normally present in lesser quantities. The complete flotation of chalcocite is achieved between ph = 1 to ph = 10 with ethyl xanthate.

PDF A Review of the Flotation of Copper Minerals
The recovery of these copper minerals by flotation or hydrometallurgy from ores typically containing 0.5%TCu open pit mines and 1-2%TCu underground mines is of great commercial importance.
Mineral Flotation - MINING.COM
Flotation has been at the heart of the mineral processing industry for over 100 years addressing the ‘sulphide’ problem of the early 1900s and continues to provide one of the most important tools.
Flotation Circuit - an overview ScienceDirect Topics
1 Introduction Flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. Froth flotation is based on differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/liquid slurry.
Process mineralogy as a key factor affecting the flotation .
Two flotation tests were conducted using the same flotation machine Denver D12 with a 4.5-L cell and an agitation speed of 1200 r/min. In both repli es the sample mass was 1175 g and the pH was adjusted to 10.5. In each test after preparation of the pulp with a specific solids concentration pulp density of 25wt% and 30wt% Z11
