A leading European Mining company operating in the DRC has awarded Roytec a contract for 4 x 145m2 Roytec TXSY vacuum belt filters. This contract follows an earlier success for Roytec in the supply of 2 x 145m2 belt filters for a new phosphate mine in the Western Cape.
The DRC contract is for copper recovery after tank leaching and employs a 3 stage counter-current cake washing system for optimum efficiency.
Roytec carried out site testwork and completed the process specification in conjunction with the client’s engineers, and a unique dual feed system allowing for a pre-coat of coarse material before the addition of flocculated fines has been specified.
The filters will be manufactured by Roytec’s partner Nuclear Industries Yantai Tongxing (TXSY) in the Shandong province of China. They are fitted with standard European and South African brand mechanical components, and are fully serviced & guaranteed by Roytec.
The 2 x 145m2 filters for the South African phosphate mine will be employed on concentrate and tailings dewatering duties allowing for a closed water circuit.
