PROCESSING OF COMPOSITE ORES OF SOUTH URAL VIA PROFOUND DIRECT REDUCTION TECHNOLOGY
The composite ores of South Ural cannot be fully processed via blast furnace technology because of high content of MgO or TiO2. The main objective of investigation was to establish optimum conditions for the production of iron nuggets from composite ores via profound direct reduction RHF (rotary hearth furnace) technology. It was found that reduction, melting and slag removal can be achieved in just 9-12 min. This preliminary test work provides valuable information which may be used for large-scale testing in a commercially sized RHF.
