Method for recovering copper, lead, silver and zinc from the copper dross

摘要

method of recovery of copper, lead, silver and zinc with copper szlikru00f3w, advantageously with a high content of copper, zinc and iron, resulting in the refining of lead from the furnace szybowego is characterized by the fact that szlikry copper making using nasiarczaju0105cego melting the reduction in temperature of the final 1373 - 1473 k with the addition of 10 - 25% galeny leaded petrol,4 - 7% carbon reducing agent and 3 - 20% flux materials containing oxides of silicon, sodium and calcium, and covering the phase reduction of oxides of lead and copper at 1073 1273 k and - phase reduction of zinc oxide in slag at 1373 - 1473 k in 1 - 3 h.
