Gold-Copper Ores - ScienceDirect

Jan 01, 2016· For oxidized and transition copper–gold ores, it is difficult to obtain an acceptable copper concentrate. The two most common approaches are controlled potential sulfidization (CPS) and the fatty-acid flotation method (Phetla and Muzenda, 2010). The selected method is dictated by the nature of the mineral makeup of the gangue, which is often complex and can play a significant role in the overall flotationCited by: 56

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

Jan 01, 2016· Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold recoveries.Cited by: 22

Gold Flotation - Mineral Processing & Metallurgy

Jul 13, 2016· In this, as in all other phases of flotation, each ore presents an individual problem and must be so studied. It was describe by the use of 600 series of flotation reagents which were developed primarily for the purpose of depressing carbonaceous and siliceous slimes in the flotation of’ gold ores. Carbonaceous material not only greatly increases the bulk and moisture content of a flotation

Optimisation of gold recovery by selective gold flotation ...

Abstract. 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

Silver Gold Recovery Flotation Process

Oct 17, 2016· The contents of the cone are then removed through a plug valve. Some 400 lb. of rich material is obtained in this way every day from the five cells, bringing the recovery of gold and silver in the grinding circuit up to 75%. This installation was one of the first large plants to prove the value of flotation in the treatment of gold ores.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Apr 18, 2016· A Flowsheet to recovery gold from sulfide ores. There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals ...

(PDF) Gold Extraction and Recovery Processes For Internal ...

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

Flotation Flowsheets

Mar 29, 2016· The Anaconda Copper Mining Company operates one concentrator for the treatment of copper sulphide ores and another for the treatment of zinc sulphide ores. The flow-sheets of the two plants are given in Figs. 50 and 51 respectively, as represented by A. E. Wiggin in the trial of the case of Minerals Separation, Ltd. vs. Butte and Superior ...

Jul 01, 1996· * Improved gold recovery: In the flotation of copper-gold ores, the Jameson cell has demonstrated superior recoveries compared to mechanical flotation cells. Additionally, in accordance with the Jameson cell's fast kinetics, the gold is typically recovered quickly (i.e. high recoveries from the first stages of both roughing and scavenging).
