This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

Froth flotation is a process for selectively separating of 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.

Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.

Copper-Lead Separation Micro-Flotation Tests. To carry out micro-flotation tests to separate copper and lead, 5 g of high purity chalcopyrite and 5 g of high purity galena with the size of +38–74 μm were artificially mixed. IPETC was used as a chalcopyrite collector. Natural pH 6.5 was used without adjusting.

Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used ...

To achieve an efficient separation in the flotation process, valuable particles need to be selectively segregated from the gangue while utilising a minimum number of flotation stages. Today's existing flotation technologies are effective for fine particle size classes; however, limitations due to particle buoyancy and bubble-particle detachment restrict the effectiveness of traditional ...

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Therefore, in all the experiments of copper-lead separation flotation and gold-lead separation flotation, the separation efficiency of the intermediate size fractions is the highest. A lower SE value of gold-lead for the coarse size fraction may be due to insufficient liberation of gold from galena or other gangue minerals.
