Abstract
A metal containing compound reduction and melting process which entails feeding a burden (15) comprising a mixture of the metal containing compound and a suitable reductant in particulate form into an electrically heatable vessel (11) which contains a bath (18) of the said metal in liquid form so that a reaction zone is formed in the burden (15) in which the metal containing compound (15) is reduced and a malting zone (23) is formed below the reaction zone in which the reduced metal is melted; and controlling such process in such a manner that substantially all of the reduction of the said metal containing compound takes place in the solid phase. Apparatus for carrying the said process into operation comprises a single compartment (11) channel type induction furnace (10) in which the said reduction and melting are carried out, the compartment (11) being provided with at least one feeding port (13, 14) for the burden (15); at least one exit port for the liquid metal product; and at least one exit port for any slag formed in the reaction.
Claims
AMENDED CLAIMS
[received by the International Bureau on 10 November 1997 ( 10.11.97); original claim 2 amended; remaining claims unchanged (1 page)]
Claim 1 A metal containing compound reduction and melting
process which entails feeding a burden comprising a mixture of the metal containing compound and a suitable reductant in particulate form into an electrically heatable vessel which contains a bath of the said metal in liquid form so that a reaction zone is formed in the burden in which the metal containing compound is reduced and a melting zone is formed below the reaction zone in which the reduced metal is melted; and controlling such process in such a manner that substantially all of the reduction of the said metal containing compound takes place in the solid phase.
Claim 2 The process of claim 1 wherein the said control of the process is effected by controlling at least one of the following parameters:
(1) the manner in, and rate at, which the burden is fed into the vessel;
(2) the particle size of the burden; (3) the degree of mixing of the burden;
( 4 ) the rate at which heat is supplied to the vessel ,
