Scope of Work
OMC worked in conjuction with Hydromet Pty Ltd (Hydromet) and Murray Hill Metallurgical Consultant to produce a Scoping Study for the Marenica Uranium Project.
Flowsheet
The Kambalda plant comprises a jaw crusher, stockpile, single stage AG mill with recycle crusher and a flotation concentrator. The AG mill is a 26ft 3.5 MW unit.
Outcome
Through recommended changes to stockpile management, mill grate configuration and control philosophy the average plant throughput was increased by 15%.
Having successfully aided site personnel in the optimization of the grinding circuit at Kambalda, OMC undertook a desk top study looking at expansion options for 1.5-2.0 times current treatment rates.
This process was undertaken over a three year period with an initial audit and modeling, a follow-up a year later and expansion modeling the year after that
