Abstract. The features are considered of binding carboxylic acids (HR) as dimeric solvated copper(II) complexes at the copper(II) extraction with chloroform under substoichiometric conditions, with excess of the metal ion in the aqueous phase.

Copper Mining and Extraction Sulfide Ores

Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about 1.3V and so the process is safe. What happens in electrolysis? Under these conditions, copper atoms dissolve from the impure anode to form copper ions.

The extraction of copper(II) and iron(III) from chloride ...

Extraction of copper with LIX 64N from sulphate media in the presence of iron is thus more difficult in that less acid conditions must be used, but selectivity for copper over iron is improved. Only a slight improvement in selectivity results from the addition of chloride.
