Jan 20, 2021 · The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles

copper extraction and purification - chemguide

Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction

optimisation of gold recovery by selective gold flotation

Feb 01, 2001 · Activators The use of copper sulphate as an activator for the surface of pyrite is common. In early studies copper sulphate was also considered to be an activator of the gold surface (Leaver and Woolf, 1934). However, more recent studies have shown it not to affect the floatability of gold using xanthate at a pH of 11.3 (Duchen and Carter, 1986)

May 01, 2000 · 1.. IntroductionIt is well known that activation of iron sulphide flotation systems with Cu(II) will provide an increase in sulphide grades and recoveries (Chang et al., 1954; O'Connor and Dunne, 1994; O'Connor et al., 1988).In most cases, when these sulphides such as pyrite, pyrrhotite and arsenopyrite contain gold, activation with copper sulphate will also result in greater gold recoveries

gold pyrite, pyrrhotite and arsenopyrite recovery

Apr 15, 2018 · Copper sulfate is often used as an activator in the flotation of gold associated with iron sulfides. Experimentally, when copper sulfate is used in the flotation of gold bearing pyritic ores, the recovery is higher and the rate of flotation is faster. The use of copper sulfate is particularly effective in improving relatively coarse particle
