2015-7-26  Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper - hence "blister copper") and then cast into anodes for refining using electrolysis. Electrolytic refining

Copper is purified by electrolytic refining of blister ...

The correct statement about this process is/are: Hint: Blister copper is an impure form of copper containing sulphur. Copper is obtained by electrolytic refining of the impure copper. Try to write the chemical reactions taking place at the anode and the cathode. The electrolyte should have the copper ion so that it can be deposited as pure copper.

Blister copper. The unrefined copper of about 98.5% purity produced from the converting step of copper smelting. Calcium ferrite slag. A slag based on CaO that contains FeO and Fe 2 O 3, which can absorb highly oxidized iron and thus is used in continuous copper converting under higher oxygen partial pressures than in conventional converting processes. ...
