Abstract

A process for producing lead and zinc from concentrates of zinc and lead sulfides or oxides includes the steps of: (a) mixing lead ore and/or zinc ore concentrates, iron bearing and carbon containing materials, metallic iron fines and iron oxide fines, carbonaceous reductant, fluxing agent, and a binder to form a mixture; (b) forming agglomerates from the mixture (c) introducing the agglomerates to a melting furnace; (d) vaporizing lead and zinc in the melting furnace, and removing these metals from the melting furnace in vaporized form; (e) cooling and condensing the metal vapors to liquid metal; (f) separating the zinc and lead; and (g) recovering each metal separately.

Abstract

A method for producing liquid ferroalloy by direct processing of manganese and chromium bearing iron compounds, by the steps: of mixing carbonaceous reductant, fluxing agent, and a binder with materials such as iron sands, metallic oxides, manganese-iron ore concentrates and/or chromium-iron ore concentrates and silica sands, to form a mixture; forming agglomerates from the mixture; feeding the agglomerates to a melting furnace with other materials; melting the feed materials at a temperature of from 1500 to 1760°C and forming a slag and hot metal; removing the slag; and tapping the hot metal as liquid ferroalloy.

Abstract

A method for producing pig iron by direct processing of ferrotitania sands, by the steps of: (a) mixing carbonaceous reductant, a fluxing agent, and a binder with titanium- containing materials selected from iron sands, metallic oxides, and/or iron ore concentrates, to form a mixture; (b) forming agglomerates from the mixture (c) introducing the agglomerates to a melting furnace; (d) melting the agglomerates at a temperature of from 1500 to 1760C and forming hot metal with a slag thereon; (e) removing the slag; (f) tapping the hot metal; and (g) recovering the titanium and vanadium values.
