Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
The most valuable elements in a polymetallic sulfide ore in the Shanxi province are copper, lead, zinc, gold and silver, and the main metal minerals are galena, sphalerite, chalcopyrite, pyrite, and so on.
Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the

Water quality, flotation equipment size and type, temperature, and ore body variation are just a few of the variables affecting the flotation process. Copper/Molybdenum Ore The figure above is a simplified flow sheet showing the basic steps involved in a copper mill producing the byproduct molybdenum.
There are two distinct types of copper ore, the sulfide ore and the oxide ore. the fine sulfide ore ~-0.5 mm going to froth flotation cells for recovery of copper. solution so the copper can be recovered at a high electrical current efficiency by
Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique.
Traditional sulphidisation flotation techniques, which are widely used on copper oxide ore, can not be used in sulphide/oxide blends for simultaneous sulphide and oxide copper flotation as the sulphidising reagent will suppress the flotation of sulphide minerals as shown within this case study.

The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation …
Consequently, aside from a few fundamental principles regarding flotation and the use of reagents, it is generally agreed each ore must be considered a problem for the metallurgist to solve before any attempt is made to go ahead with the selection and design of a flotation plant.

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
Beneficiation of Copper Sulfide by Flotation. Copper, due to the present world demand and price, is of foremost interest to the mining industry.Many new properties are either in the process of being brought into production or are being given consideration.

1. Introduction. Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulphide minerals (Herrera-Urbina, 2003).This process is based on the wettability of mineral particles to recover the mineral species of interest and depress unwanted gangue.
