Process for the electrolytic extraction of copper from its ores.
EMI1.1
If carried out without a diaphragm, local effects arise when using concentrated Lusuugeu and low current densities. These effects stem from the fact that the copper deposited on the cathode dissolves again in the ammoniacal cupril
EMI1.2
This double transformation causes a small loss of electrical energy, which reduces the yield of pure copper, which can be almost entirely avoided if the ammonia is replaced by ammonium carbonate. This can be done in the
EMI1.3
or sulfite is replaced by ammonium carbonate, or that the precipitate of copper oxydulfite or copper oxydulfite is dissolved in a solution of ammonia or in an ammoniacal solution of ammonium sulfate or sulfite and the solution with

Trolyse also has the known advantage that the electrolyte is set in motion.
