At some mines, washing is combined with the screening of fines ( 6 – 8mm) for sintering process. The predominant portion of iron ores must be conducted the beneficiation process; very fine material containing alumina content is reduced. In the enrichment process the gangue will be reduced and in many cases; its composition improved.

The tailings, hydrocyclone overflow, on the other hand, are fed to a tailings thickener. The overflow of the tailings thickener (clarified water) is recirculated back and caters to the process water requirement of the plant. The recovered process water from the tailings thickener overflow of about 90–95% is recycled back to the process plant.
