Extraction of Copper from Copper pyrite Reference Notes
Report Here. The principle 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.
(PDF) Effects of the Addition Points of Reducing Agents on
Sodium determine the effects of SMBS addition points on the metabisulfite (SMBS) is one of the most commonly rec extraction behaviors of copper and cobalt. SMBS was ommended reducing agents [1, 3], but its addition during added to various aqueous solutions at time t = 0 and leaching could significantly affect copper recovery if pre t = 3 h.
Extraction Of Copper Application Of Metallurgy Chemistry
Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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.
EXTRACTION OF COPPER uotechnology.edu.iq
EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.
copper extraction and purification chemguide.co.uk
Extracting copper from other ores. Copper can be extracted from non sulphide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
Copper Recovery by Solvent Extraction Techniques
Assuming total labor costs of about $24 per ton of copper produced, the overall operating costs of solvent extraction plus electrowinning can be as low as $72 per ton of copper. For cement copper production freight and smelting charges alone usually exceed this figure.
