PROCESS FOR THE EXTRACTION OF NON-IRON METALS FROM RESIDUES THAT CONTAIN IRON

摘要

Non-ferrous metals are extracted from iron-bearing scraps by adding the scraps and a slagging agent for iron to a molten copper bath, injecting an oxygen containing gas in the bath and keeping the bath temperature below 1400 DEG . The scraps thus undergo an oxidizing smelting in the presence of a molten copper phase and a slagging agent for iron, resulting in a rapid extraction of non-ferrous metals from the scraps into the copper phase and a thorough iron slagging.
