:: Hatch Provides EPCM Services for Copper Mine
Hatch is providing Taseko Mines with engineering, procurement and construction management services for three expansions at the Gibraltar copper mine north of Williams Lake, British Columbia. The project includes the addition of a stand-alone SAG milling facility with a 34’ SAG mill and high-angle feed conveyor, discharge vibrating screen, associated re-circulating conveyors and slurry pumping system.
Integral to the expansions are the modifications to the existing conveyor feed system, conversion of the existing rod/ball mill circuits into six-ball mills operating in parallel, and improvements to the existing flotation system, where the existing 600 cu.ft. Denver cells are being replaced with OK160 Outokumpu tank cells.
The existing substation is also being expanded to provide the additional load required for the increased plant throughput.
Hatch completed the scoping level trade-off study in March 2006, comparing process expansion alternatives for the mine, and evaluating expansion opportunities with consideration to changes in process technologies and equipment.
On completion of the trade-off study, Hatch was retained to continue with basic engineering in order to develop the chosen expansion option, and shortly thereafter was awarded the full EPCM contract.
Engineering and procurement for the Stage 1 Expansion Project is substantially complete, while construction is in progress and scheduled to be completed by February 2008.
Basic engineering has started for an additional plant expansion (stage 2) and for a new in-pit crusher installation as to finalize concepts and procure long lead items parallel to the construction activities of stage 1. Construction activities are expected to start in early 2008, with commissioning scheduled to be completed by September 2008 for the in-pit crusher, and early 2009 for the stage 2 expansion.
