Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Pyrite flotation from gold leach residues ScienceDirect

01/05/1994· The flotation of auriferous pyrite in gold leach residues through traditional techniques is only possible after conditioning with sulphuric acid toe depression by cyanide and hydroxide. Recent testwork at both GENMIN Process Research and on site at Buffelsfontein Gold Mine suggested that the auriferous pyrite contained in the cyanide residues could be floated by using an amine as a collector.

Gold Flotation Mineral Processing Metallurgy

13/07/2016· Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite.

4 Extraction Processes for Gold Pyrite Ore

21/10/2020·ł. The Extraction Processes of Gold Pyrite Ore. The treatment principle of gold pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation.

How to reduce pyrite content from gold concentrate Froth

Natural pH ismended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered.
