VANCOUVER - ADANAC MOLY CORP. says it will opt for high pressure grinding rolls (HPGR) rather than SAG milling in the processing plant for its Ruby Creek molybdenum project.
A report produced by WARDROP points to significant reductions in operating costs and more plant uptime using HPGR. Overall on-line power demand for the nominal 20,000-tonne/day concentrator and infrastructure is expected to be reduced from 19.2 to 16.5 MW. With the HPGR option, process plant availability will be increased from 91% to 96% which equates to an additional 400,000 tonnes milled annually, from which 2.6 million lbs Mo will be added to production in the first five full years of operations.
Adanac says it expects the HPGR option to add $22.5 million to the initial capital cost of the project, but that the technology will result in an extra $41.4 million in gross revenue at current molybdenum prices.
