 · REFINING OF COPPER Blister copper is refined by electrolysis. Blocks of blister copper are casted to use as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO 4) mixed with a little amount of H 2 SO 4

Light the microburner and begin to heat the copper oxide in the tube. Keep heating for a minute or two and watch for changes occurring in the tube. When there are no more changes, stop heating, wait for a moment, and then try to light the gas coming out of well F1. Blow out the microburner and detach the lids from the Comboplate®.
