Recovery of Cu and Zn from Complex Sulphide Ore - IOPscience

As Zinc and copper often occur together, the separation of one metal from the other has presented problems to the nonferrous metallurgists [1]. Sulphide ores are extremely complicated mineralogical associations of the inter grown of their constituent minerals [2] comprising mainly chalcopyrite (CuFeS2), sphalerite (ZnS),.

A study on selective flotation in low and high pyritic copper sulphide .

The effect of chemical reagent configurations was investigated on two different copper sulphide ore types, including high and low pyritic feeds. Three different combinations of collectors as isopropyl-n-ethyl thionocarbamate (C-4132), mixture of mercaptobenzothiazole and butyl sodium dithiphosphate (Flomin 7240) and.

A new way of extracting copper | MIT News

Jun 28, 2017 . In a cell that used only copper sulfide, for example, because of its high electronic conductivity, the extra electrons would simply flow through the electrolyte without interacting with the individual ions of copper and sulfur at the electrodes and no separation would occur. The Allanore Group researchers.

copper extraction and purification - Chemguide

Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method.

How do i separate gold from sulphides without using chemicals or .

My freind has a large supply of microscopic gold particles, however they need to be separated from sulphides. there is a high concentration of gold in this solution, and millions of dollars could be made. however, heating the sulphides will make sulpheric acid, which burns away your lungs (also used in chemical warfare).

How Sherritt Refines Nickel

Oct 1, 2010 . Copper Separation. The dissolved copper is removed in this section of the plant. The blended nickel-rich solution is heated in distillation pots to drive off ammonia. As the pH is lowered, the copper, unsaturated sulphur compounds and elemental sulphur combine to form solid copper sulphide. The slurry is.

May 12, 2017 . Abstract: The mineralogical characteristics of enargite-bearing copper ores from the Tampakan deposit have been investigated as the means to understanding the separation of enargite from other copper sulphides (chalcopyrite and bornite). It was found that a separation of these minerals was possible.
