Abstract
The invention relates to a pyrometallurgical process for the treatment of complex metal ores, such as oceanic nodules, containing, in particular, manganese and copper, in which the ores are subjected to reducing fusion to produce a primary slag, containing all the manganese, and a primary alloy containing copper, nickel and cobalt. The primary slag which is then decoppered, may be used for the production of ferro or silicomanganese, while the secondary alloy is recycled for the reducing fusion step.
