Mining and minerals processing equipment manufacturer FLSmidth is in the process of delivering an EIMCO ® -Clarifier-And-Thickener (E- CAT ® ) and a Shriver ® filter press to Mopani Copper Mines in Zambia for its Mufulira Smelter. The equipment removes and dewaters dust particles from the water system. Ricus van Reenen, Sales Manager: Products at FLSmidth, ex- plains that FLSmidth’s E-CAT ® technology, which boasts no moving parts at all, combines optimised flocculation, high rate clarification and high density in a single compact unit. It streamlines liquid-solid separation flow sheets by optimising chemical settling aids and providing a dedicated escape route for displaced free liquid. The fact that there are no moving parts translates into a lower cost and lower energy consumption, meaning reduced maintenance in the long run. The E-CAT ® also has a smaller surface area than con- ventional thickeners, and therefore a smaller footprint that optimises space on constrained sites, particularly in remote locations in Africa. In addition, the self diluting feedmakes for optimal flocculant utili- sation, while no external dilution pumps are necessary either. Good overflow clarity means that effluent can be re-used, while the dense underflow cuts down on the energy needed for drying. The smaller ponding area necessary also means a reduced handling volume.
