The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck
The Testing And Concentration Of A Low Grade Copper-Nickel Ore., Laurence T. Eck
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to investigate the possibility of concentrating a low grade copper-nickel ore, to determine the most effective method of concentration, and to attempt to draw some conclusions to determine whether or not the concentrates produced would be of sufficient high grade to make the recovery of nickel and copper a profitable enterprise.
The Recovery Of Copper In Sulphide Ores By Roasting, Leaching, And Electrolysis, Jack S. Greenough
The Recovery Of Copper In Sulphide Ores By Roasting, Leaching, And Electrolysis, Jack S. Greenough
Bachelors Theses and Reports, 1928 - 1970
Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition. The problem is to convert the sulphide into the oxide form. This can be done by giving the sulphide ore an oxidizing-sulphatizing roast. Copper sulphate is soluble in water, so acid will be saved in the leaching process if copper sulphate is present. The iron in the copper sulphide ores is present as pyrite, or in combinations as bornite, or chalcopyrite.
A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel
Bachelors Theses and Reports, 1928 - 1970
The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.
