Project Category:

Optimisation

Client:

BHP Billiton Nickel West Pty Ltd

Location:

Western Australia

Commodity:

Nickel

 

 

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
