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. The processing techniques depend on the nature of …
How does the copper extraction process work? Most copper is refined from sulphide ores. The process includes the following stages: The copper ores are mechanically crushed and ground. The resulting mixture i s treated using flotation with air injection and agitation to leave concentrates containing around 30% copper.
Copper/gold concentrate produced at the Minto mine is loaded onto trucks headed for Alaska. En route, the concentrate trucks must cross the Yukon River by barge or ice bridge. Our first stop is Skagway, Alaska When the concentrate arrives at the Skagway Ore Terminal, it’s stored until there is a sufficient load to be shipped to Japan.

This conversion 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. As in all mining operations, the ore must usually be beneficiated concentrated . To do this, the ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it und…
The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds. Reaction in the flash smelting furnace
The Basics of Copper Mining and ProcessingWhat Is Copper Used for?The Copper Mining ProcessOnce it’s lo ed within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. These eight stages include: 1. Mining 2. Grinding 3. Concentrating 4. Roasting 5. Smelting 6. Conversion 7. Anode Casting 8. Electro-RefiningDocumentation of the use of copper dates back to ancient times. The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production.During the
Copper concentrates are mostly from sulfide ores. Ores extracted from overseas mines have a typical grade of about 1%. The ores are processed at the mines to increase the Cu content for concentrate. COPPER ORE CONCENTRATE OF 22% 25%
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral ore . Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main
Copper and molybdenum-containing ore being mined by Codelco in Chile. The pulp from this grinding process is introduced into a floating process to which water and chemical reactants are added. This process results in a collective concentrate, Cu-Mo, containing approximately 30% copper and 1% …
Froth flotation to separate plastics, Argonne National Laboratory Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.
