Sulphide Flotation - an overview ScienceDirect Topics

A great number of base metal sulphide flotation plants use saline water. Some of them are summarised in Table 1. The three nickel flotation plants (Mt Keith, Leinster mine and Kambalda Nickel Concentrator) in Western Australia operated by BHP Billiton use bore water with high ionic strength.

2021-7-8  For a number of years a mine struggled to float a sulfide mineral and was getting less than 50% recovery even after installing a rotor and stator “upgrade”. We did minor modification to the rougher float cells and achieved a 19% increase in recovery. These improvements would apply to all flotation cells.

1 Froth Flotation – Fundamental Principles

2009-8-27  The collectors available for flotation of oxide minerals are not as selective as the collectors used for sulfide mineral flotation, as they attach to the surface by electrostatic attraction rather than by chemically bonding to the surface. As a result, there is some collector adsorption onto the minerals that are not intended to float.
