Raji O. Improvement on preprocess technology and utilization of metallurgical slurries

Research object - sintering technology and treatment of zinc-bearing slurries with molten steel smelters slag. Purpose of work - development of effective solutions for improving sintering production process mostly on red-mud usage and energy-material saving technology pyro-metallurgical treatment of waste dezincing. Research methods - theoretical and statistical methods. Experimental research - laboratory sintering of charge mix in sintering pan diameter 200 mm. Prospect of organizing pyro-metallurgical technological circle to treat red-mud and zinc-bearing slurries of ferrous metallurgy are estimated. Physical, chemical, minerals and roentgen structure of slurries are studied. Principles of steel smelters dust non-ferrous metals saturation are established. Processes and preparation technology to obtain aluminous agglomerate with charge mix mainly on red-mud are investigated. Methods of preparation of zinc-bearing blast-furnace slurries for treatment by pyro-reduction processing are developed. Material-energy saving pyro-reduction treatment technological chart dezincing of zinc-bearing slurries by molten steel smelter slags is designed. Application area - Project and research institutions, metallurgical industries and educational institutions.
