Improve the efficiency of EW cells

From Chile, SELE (Selective ELectrodeposition Enhancer) is a custom-designed device from New Tech Copper (NTC) for installation in electrowinning cells. Cathodes and anodes are confined within SELEs and this significantly enhances the copper extraction process by eliminating short-circuits and the use of spacers. NTC says the technology improves the physical quality of cathodes by 30 to 60% and the chemical quality by 10 to 40%. Additionally, there is a 5-7% increase in current efficiency. There is a reported 100% saving on service contracts – no need for: Shorts supervision Installation and supervision of plastic strips and anode spacers Manual cathode stripping and quality packaging CathodeImprove the efficiency of EW cells

Best practice in mineral processing

Best practice in mineral processing

Industry leaders agreed to two complementary strategies to drive forward best practice in mineral processing at the 2014 CEEC Workshop. Endorsing the work of the Global Mining Standards Group (GMSG), the Workshop delegates embraced the initiative led by the GMSG Industrial Comminution Efficiency team in generating global guidelines for standardised measurement of operating loads. Using standardised measurement processes will facilitate the generation of comparable data, essential to process optimisation. Additionally, the work of Dr Grant Ballantyne (The Julius Kruttschnitt Mineral Research Centre JKMRC) surveying the comminution energy requirements of gold and copper producing mines has provided reliable benchmarking data.

Gabon mining sector project awarded to GAF

Gabon mining sector project awarded to GAF

GAF AG, Germany and its partner Sofreco, France, have been awarded the “Renforcement des Capacités de l’ Administration des Mines" contract and the initiation of activities in Gabon. The client and beneficiary is the Ministry of Mines, Industry and Tourism in Gabon. The project has been launched as a response to Gabon’s request for assistance in developing its mineral sector. The project addresses a challenging portfolio of activities in the field of geological and environmental mapping, mineral potential assessment and institutional strengthening. The key aspects include: Geological and geotechnical mapping of the cities of Libreville and Owendo Mapping of environmentally sensitive areas inGabon mining sector project awarded to GAF
Conveyor system chutes successful with sticky ore

Conveyor system chutes successful with sticky ore

Weba Chute Systems has supplied eight chutes to a copper mine in the DRC. This follows on from an initial successful order for four transfer towers for an overland conveyor system. Ted Cruickshank, Project Manager explains: “We had to design for ore conditions that were extremely sticky. The bulk density of the material is 1.7 and the maximum lump size is 375 mm. The belt width is 1,200 mm and design capacity is 1,500 t/h with a belt speed of 1.9 m/s. Designing these chutes posed a major challenge in that the material has a 60:40 fines ratio.
