Copper Smelting an overview ScienceDirect Topics

This reagent is widely used in the selective flotation of leadcopperzinc and copperzinc ores to depress sphalerite, pyrite, and certain copper sulfides. Sphalerite rejection from copper concentrates is often of major concern, as zinc is a penalty element in copper smelting. Cyanide chemistry is comprehensively reviewed by Guo et al

Extraction Of Copper Mining, Concentration, Smelting

Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of

3 Technologies in Exploration, Mining, and Processing

The copper ore bodies mined from 1 to 1938 at Kennecott, Alaska (now within the WrangellSt. Elias National Park and Preserve), are examples of potentially environmentally friendly ore deposits. and the volume of the flotation cell may not be the dominant factor. Flocculation technologies are used in the ironore industry to

Mineral processing

Froth flotation cells used to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. This separation technique can be useful in mining iron as it is attracted to a magnet. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and

Flotation Mineral Processing Metallurgy

Jan 11, 2016· The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations

Platinum Mining and Refining Education

Froth generated at the top of a flotation cell concentrates the platinum particles. The dried powder is then heated to extremely high temperatures to remove impurities. Air is blown over the matte that remains after smelting to eliminate unwanted iron and sulfur. At this point, the PGM content of the matte is now about 50 ounces (1.4 kg) per ton.

Copper

Copper is a chemical element with the symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkishorange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling
