A procedure for the Recovery of non-ferrous metals from Metallurgical Waste containing these Metals

摘要

A procedure for the Recovery of non-ferrous Metals, including Copper, nickel and Cobalt from Waste containing these Metals Nonferrous Metal in an oxidation State greater than or equal to Zero, in an electric arc furnace of plasma type AC com Light a Plurality of electrodesWhich contains a plug of liquid copper slag covered by a FluidThat includes at least one phase of Iron reduction; consisting of: load the Metallurgical wastes including non-ferrous Metals on the block is in the electric arc furnace Melting residues in plasma; the slag Fluid or at the interface of Metal: Reducing slag Bath R at least Nonferrous Metals to Zero oxidation State; and Shake vigorously the taco cobrAnd through the Injection of Inert Gas, preferably nitrogen or argon, in such a way as to avoid the formation of crusts and accelerate the reduction reaction to make the non-ferrous Metals miscible in Copper in the Copper Block.
