A METHOD FOR DIRECT REDUCTION OF OXIDIZED CHROMITE ORE FINES COMPOSITE AGGLOMERATES IN A TUNNEL KILN USING CARBONACEOUS REDUCTANT FOR PRODUCTION OF REDUCED CHROMITE PRODUCT/ AGGLOMERATES APPLICABLE IN FERROCHROME OR CHARGE CHROME PRODUCTION.

摘要

This invention relates to a method for direct reduction of oxidized chromite ore fines (0 to 4.0 mm) composite agglomerates in a tunnel kiln to produce one of a reduced and agglomerates for use in ferrochrome or charge chrome production; comprising implementing a direct reduction or solid state reduction of oxidized chromite ore fines in a tunnel kiln using carbonaceous reductant such as coal, anthracite or charcoal.
