Gold Extraction Methods from different types of gold ores ...

In addition to pyrite, natural gold is closely associated with copper, lead and other minerals. The particle size of natural gold is coarser, but the grain size varies widely and distributes unevenly, and varies with the mining depth. This kind of ore is generally treated by flotation method to concentrate the gold in the non-ferrous mineral ...

11/01/2016 · What Ore is Suitable for Flotation. The largest class of ores treated by the flotation process consists of those containing the sulphide minerals of copper ; these sometimes contain native copper and also gold and silver, all of which can generally be floated with the sulphide minerals in one concentrate. Any pyrite or other iron sulphide present can usually be

Coarse and Fine Particle Flotation Recovery

02/06/2016 · Coarse and Fine Particle Flotation Recovery. Post navigation. Previous. Next . In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch,

Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery

15/04/2018 · 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 flotations involving pyrite. The

The Effect of Sulfurization Process on Flotation of Copper ...

It was determined that gold and silver could not be reached with satisfactory yields by flotation of original ore at the defined size. Thus, original ore was sulfurized before the flotation. By the flotation of the sulfurized ore, it was seen that Au, Ag, Cu, Zn and Co were collected with fairly high yields in the concentrate phase. In the optimum flotation conditions, all of gold, 96.52 %

Gold Recovery 101 - Sepro Systems

While gold is naturally hydrophobic and thus amenable to flotation in the particle size range of 75-300 µm, very fine or very coarse gold does not respond well. Along with the benefits of lower CAPEX and reagent consumption mentioned previously, this can make the addition of a gravity circuit even more critical as it will prevent overgrinding of gold and capture any coarse

Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal. The flotation method of concentration, used extensively for other metal ores, has only recently

The Grinding Fineness- the Factor Affecting Gold Leaching

25/03/2020 · Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage,

can influence the behaviour of gold in flotation, leaching and/or recovery processes. Electrum with a high silver content may give poor gold extraction due to tarnishing of the silver (Fleming, 1998). The presence of copper in the ore at above ±0.3% concentration may make direct cyanidation uneconomic without re-treating the Cu(CN)2 formed
