Extraction of Copper from Copper pyrite | Grade 12 Science,

The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.Copper Mining and Extraction Sulfide Ores,Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore.

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide OresExtraction of copper from copper pyrites (CuFeS2,,Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2-----> SO 2 4AS + 3O 2----Copper extraction by wet chemical method - ScienceDirect,Jan 01, 2018· A graph of mass of the ore used in the extraction against mass of the precipitate produced. The results show that the amines and uric acids in chicken waste can complex copper ions from ores just like the acid leached solution. Therefore the copper ions obtained from 6.0 g of the ore were later reduced by hydrazones species prepared in situ.

The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.Innovations: Introduction to Copper: Mining & Extraction,Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
