Abstract
A new route from copper concentrate to metal includes 2-stage fluid- bed treatment; pelletized concentrate (33 percent cu, 7 percent s) is first desulfurized (to about 0.5 percent s) in an oxidizing atmosphere. In the second stage, the calcine is metallized by reduction with hydrogen. Thereafter, the reduced product plus 10 percent cao is routed to a smelting furnace to separate metallic copper from the gangue. Pelletizing the fine concentrate into minipellets prior to fluid-bed treatment permits shorter reaction time and decreases dusting.
