FIELD: metallurgy.
SUBSTANCE: method of leaching of high-carbonate copper ores includes ore irrigation by the leaching agent solution which is the solution of carbonate of alkaline metal with the concentration 10-100 g/dm3. At first the ore irrigation is conducted continuously until achievement of minimum 10% copper extraction into the solution. Then the irrigation is conducted with pauses up to 10 days. The alkaline metal carbonate is sodium or potassium carbonate.
EFFECT: high selective extraction of copper into solution.
