FIELD: metallurgy.
SUBSTANCE: invention relates to processing into blister copper of cupriferous sediments formed as a result of the cementation of cupriferous mine and underspoil waters. The cement cupriferous sediments of the neutralisation of the mine and underspoil waters are pre-dried in a drum drier at the temperature of 100-200°C until full removal of mechanical moisture, the resulted calcine amounting to 70-75 wt % is mixed with a reducer in the form of shredded copper matte with the fraction -1 mm taken in an amount of 25-30 wt %, the resulted mix is melted in the arc furnace, slag is pumped away, then the smelt is overheated up to the temperature of 1200°C and blister copper is poured out.
EFFECT: producing blister copper with the copper content of 92-98%.
