Copper Concentrate Process 15876

The result is a copper in concentrate of 50-60% together with the gold. The iron passes into solution accompanied by other impurities such as cobalt, nickel, zinc, lead, bismuth, thorium and its daughter products, and uranium and its daughter products. The process can be carried out in sulphate or sulphate-chloride media.

Abstract Outokumpu has developed a new chloride leach process, called HydroCopper®, to treat copper concentrates. Chalcopyrite is quite refractory in leaching and in sulfate milieu an

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Global production of copper concentrates is expected to increase by 3% year-on-year from 2015 - 2024. Arsenic is the main impurity present in copper concentrates, and is predicted to be above penalty limits in 10% of all copper concentrates produced in 2015.

Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper's flow through the economy are the mining companies, which process vast quantities of low-grade ore, mostly from open-pit mines in order to produce copper.

Copper Mining and Processing: Processing of Copper Ores Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, …

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate facilities.
