Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.
Flotation is commonly used to concentrate copper sulfide minerals, such as chalcopyrite (CuFeS 2). In this example, the production of a copper concentrate is investigated. After mineralogical examination, we decided to divide the ore into four species for characterization: Cp ( CuFeS 2 ), CpPy (95% CuFeS 2 - 5% FeS 2 ), PyAs (70% FeS 2 - 30 ...

For example, the mixed flotation process of copper zinc ore is to float all copper and zinc to obtain mixed concentrate and waste tailings. The mixed concentrate is reground or de medicated, and ...
Production of copper concentrate that can be used for extraction of copper. 4. Salient Technical Features including Competing Features. The process is based on froth flotation of copper bearing minerals from ore after milling. The concentrate is dewatered and used for extraction of metal by pyro-metallurgical route. 5. Level/Scale of Development
Flotation is the common copper processing technology, which can be used for sulfide ore and oxide ore. The copper flotation plant usually includes following steps: crushing and screening, stage grinding and flotation, thickening and dewatering, and copper concentrates recovery.
Figure 154 is a flow sheet of the flotation section of the Britannia concentrator. Here "the flotation treatment comprises first the production of bulk concentrates which contain the chalcopyrite and. pyrite with minor amounts of gold and silver. The bulk concentrates are dewatered and, after additional grinding, are again subjected to flotation.

Creating copper concentrate The ore mined on site is first ground into a flour-like powder, says Zanetti. A flotation process removes waste rock. The resulting bulk concentrate is sent to a smelter, which produces a high-grade material containing both nickel and copper. Another flotation process separates the nickel and copper concentrates.
