The first class includes copper, lead, lead-zinc, copper-zinc, and copper-lead-zinc ores. Both gold and silver may be present, the gold values being usually associated with chalcopyrite and pyrite, and the silver with galena and tetrahedrite. Flotation follows ordinary standard methods, modified as may be.

Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

Abstract— The present study investigates the effect of regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (0.07% Cu,. 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher.

Optimisation of gold recovery by selective gold flotation for copper .

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.

Gold Flotation - 911 Metallurgist

Mar 17, 2017 . 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.

Froth flotation - Wikipedia

The American Institute of Mining Engineers presented Callow the James Douglas Gold Medal in 1926 for his contributions to the field of flotation. By that time, flotation technology was changing, especially with the discovery of the use of xanthates and other reagents, which made the Callow cell and his process obsolete.

Separation efficiency improvement of a low grade copper-gold .

Newcrest's Telfer gold mine, located in the South Western area of the Great. Sandy Desert in the Paterson Province of Western Australia, processes low grade copper-gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80-160.

Gold-Pyrite ores - Danafloat

surface for collector bonding, collectors for silver indirectly also result in gold recovery. Consequently, gold flotation recovery requires a focus on floating the associated base metals (predominantly lead, copper) and often pyrite minerals. While lime is often used in base sulphide mineral flotation, because excess lime also.

Flotation Collectors | CYTEC SOLVAY GROUP

Designed to operate across a broad range of alkalinity levels and provide faster flotation kinetics, our flotation collectors have become the industry standard in the recovery of copper, gold, molybdenum and other metals. AEROPHINE®, AERO® and AEROFLOAT® collectors (promoters) are used extensively for the flotation.

deposits where gravity concentration can recover a significant fraction of the contained gold or copper prior to further processing by CIP or flotation. The process involves leaching under controlled intensive cyanidation conditions followed by selective gold absorption from the mixed gold copper leach solution onto Aurix®.
