Methods Used To Separate Copper Ore From Other

Copper Mining From Ore To Copper. About 80 of all copper extracted comes from sulphide ores. A typical ore contains only 0.5 to 2.0 copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock called gangue. The most common copper. Get Price

The Separation of Copper and Nickel from Ni- Cu Mixed

Leaching solution of Ni-Cu mixed ore was studied using electrochemical methods to separate the two ions. This was observed through investigating the electrochemical behavior of copper and nickel ions separately in acidic mediums of copper sulfate and nickel sulfate solutions. To selectively deposit copper from Ni-Cu leaching solution, potentiostatic deposition was applied and the current efficiency was

SOLVENT EXTRACTION AND SEPARATION OF COPPER

2017-9-26  Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase comprising of 30% Versatic 10 acid at the equilibrium pH of 5.0 using the phase ratio of 1:1 whereas, zinc extraction was noticed at above pH 5.0. On the other hand the pH0.5 values were 3.5 and 4.6 for zinc and copper respectively with 20% Cyanex 272. The difference in pH0.5 value of 1.10 indicated the possible separation of Zn and Cu. By McCabe Thiele diagram number of stages required for the counter current extraction of copper

Copper Mining and Extraction Sulfide Ores

The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated.
