CASE STUDY

Mine Cooling & Air Compression Hire

The Client: Minara Resources

Process cooling and compressed air on remote mine site prove to be cost-efficent and increase mine’s capabilities.

The Background

Minara Resources is one of Australia’s top nickel producers and  operates the Murrin Murrin nickel cobalt site in Western Australia’s north-eastern goldfields. Conventional open pit mining techniques are used followed by ore processing (comprising pressure acid leaching, mixed sulphide precipitation, cobalt refining and nickel refining).  Ammonium sulphate is also produced as a by-product.

The Requirement

EPSA was directly approached by Minara Resources to provide  a competitive quote for power generation, process cooling and compressed air  supply to the Murrin Murrin site. Our initiatives, proven cost efficiencies and broad capabilities for service were  integral to our success.

The Solution

Our contract is to supply 20kVA – 2000kVA power generation to the entire Murrin Murrin site for outages, planned shutdowns and maintenance. Temperature control equipment does not form part of the contract but we are given first right of supply. There is also a  bi-annual requirement for 12MW of temporary power for the  main power station during shutdown maintenance, a process that can last for up to three months.

Cat generators and temperature control products including:

  • PM1500 generators
  •  1 additional 810kVA generator for eight months
  •  Acid converter cooling package consisting of CAT 600kVA generator, 700kW chiller, 2 X 450kW air handler units, pump, buffer tank, cables, ducting and other ancillary requirements.
