JANUARY 2017 • E&MJ; 51 www.e-mj.com PROCESSING SOLUTIONS fi rst supplier to utilize it for fi lter cloths. The company said it developed the ap- plication in cooperation with customers and fi lter manufacturers, and although it is currently being offered just to the mining industry, it plans to broaden its use to fi ltration processes in other indus- try sectors. Sepro Buys Agitator & Pump Specialist Canamix Sepro Mineral Systems Corp. has ac- quired Canamix Processing Systems Ltd., which produces agitators, attrition cells, and pumps for the North American and international markets. Canamix has been in operation since 2009 and offers equipment solutions fea- turing high-quality agitators and the larg- est peristaltic pumps in the world, manu- factured in British Columbia, Canada. Recently, Canamix products have been incorporated into key Sepro offer- ings including Sepro leach reactors and Falcon gravity concentrate decanting systems. The acquisition, according to Sepro, will further create opportunities for sharing knowledge, exploring new research and development projects, and implementing continuous improve- ments in existing equipment lines for both companies. Sepro believes Canamix customers will benefi t from increased international support for products and services. Cana- mix products will continue to be sold in- dependently or as part of complete Sepro supplied solutions. Brucejack Project Selects Veolia for Effl uent Treatment Veolia Group, through its subsidiary Veo- lia Water Technologies Canada, has been chosen by Pretium Resources Inc. to sup- ply an effl uent treatment facility for the Brucejack gold mine in British Columbia, Canada. Brucejack is one of the largest and highest-grading gold projects in the world, with commercial production target- ed for 2017. Veolia said it will supply proven propri- etary processes to treat up to 10,000 m 3 per day of effl uent water from the mine. The permanent effl uent treatment system will involve several technologies, starting with the Actifl o clarifi cation process for primary metals removal. The water will be further polished by a Hydrotech Discfi lter to provide added assurance in meeting stringent discharge criteria. Startup of the new effl uent treatment facility is scheduled for spring 2017. Veolia said the contract award follows months of collaboration and testing to en- sure that the most stringent environmen- tal discharge limits will be met. Test work that was carried out at Veolia laboratories in Montreal has been used in support of the permitting work done by Pretium for the Canadian and Provincial authorities. Veolia started working with Pretium in spring 2014 when the company need- ed to dewater Brucejack's underground workings during its exploration phase. Veolia then supplied a Mobile Actifl o wa- ter treatment plant, which it has operated since. This temporary facility, according to the two parties, has provided Pretium with much valuable seasonal operational data for future reference. As the Actifl o clarifi cation process will also be installed in the new effl uent treatment facility, it gives Pretium confi dence that the sys- tem meets the requirements of low level metals and Total Suspended Solids (TSS) while dealing with variable feedwater, said Veolia. rbauction.com/privatetreaty Late-model mining assets available through Ritchie Bros.
