Introduction to Mineral Processing

A copper starter sheet functions as the cathode, and additional copper deposits on the surface of the sheet When the copper cathode has reached a certain size it is removed from the electrowinning tank, washed, and prepared for sale...

The Role of Sulphuric Acid in Copper Plating

(2004) A The sulfuric acid in a copper electrolyte is there for two reasons, one is to keep the copper in solution, you only used a 0,1 m solution, if you use higher concentrations your copper sulfate will partially get Cu(OH) 2Also the sulfuric acid gives you a better conductivity and with this comes a ,...

METALLURGY OF COPPER

Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathod The cathode plates are coated with graphite in order to remove depositing copper The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity...

copper extraction and purification

Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below) The anodes for this process were traditionally lead-based alloys, but newer methods use titanium or stainless steel...
