Townsville Copper Refinery

MIM's copper refinery in Townsville is one of the world's leading electrolytic copper refineries producing 99.997% pure LME Grade A copper cathode.

The Townsville refinery treats copper anode from Mount Isa.

The refinery has a capacity of 270,000 tonnes of refined copper a year. This accommodates the throughput from Ernest Henry (concentrate initially to Isa for smelting) and the continuing output for Mount Isa's copper mine and the Enterprise mine.

The refinery uses the MIM-developed ISA PROCESS which uses permanent stainless steel cathode motherplates in association with automated copper cathode stripping machinery. This development represents the biggest single advance in copper refining since the late nineteenth century.

Conventional electrolytic refining uses starting sheets of pure copper. The use of permanent stainless steel cathode plates eliminates the use of starting sheets, thereby reducing the labour component above all costs of refining operations.

The ISA PROCESS is licensed worldwide (53 licensees currently) and is used to produce more than 35% of the western world's refined copper.

The Townsville refinery expansion incorporated the latest ISA PROCESS Technology advances and innovations.

Some of the innovative features of this modern refinery include:

  • Corrugation of cathodes to promote more efficient melting of the copper bundles in shaft furnaces - customers select the frequency of corrugation in a bundle
  • Capability to produce two sizes of cathodes: 50 kg and 80 kg nominal piece weights
  • Bundle sizes selectable up to 3.6 tonnes, and
  • Bar-coded labels for improved identification and product tracking.
  • The modernisation of the refinery equipment and operations has enhanced the existing high standards of quality and reliability of cathode production allowing for:
  • Improved operating efficiencies to provide the conditions for production of copper of the highest purity levels
  • The management of ISO9002 accredited quality system to ensure the highest standard of copper cathode
  • The continuation of the longstanding reputation of ISA Brand LME Grade A registered copper.
  • Townsville is the distribution hub for MIM's base metal operations in Australia:
  • Rail and road links to Mount Isa and the southern states allow for the efficient and rapid delivery of copper to customers
  • The thriving Port of Townsville is the ideal base for a fast, direct shipping service to Asian and European destinations
  • Our bulk product receival, storage and shiploading service allows us to deliver concentrates, fertiliser and other bulk mineral products to the competitive markets in Asia and Europe.

History

In early 1956 the name Copper Refineries Pty Ltd was registered as a subsidiary company of Mount Isa Mines Limited for the purpose of constructing and operating a copper refinery in Townsville.

Land was acquired at Stuart near Townsville in a location that had many advantages arising from proximity to rail routes, ample area in an industrial district, reasonable access to Townsville wharves, access to the labour force of the city and other facilities such as electric power and general services.

Following the refinery's construction, it was officially opened on 2 October, 1959 by the then Premier of Queensland, the Hon. G.F.R. Nicklin. Initial production capacity was 40,000 tonnes a year.

Townsville Port Operations

Bulk Handling

The bulk handling operation is designed for bulk mineral product export and with the expansion of the North-west Minerals Province, this facility has grown rapidly.

Mineral products are delivered by rail, tippled and placed in storage prior to ship loading. Under cover storage capacity is 15,000 square metres.

Ship loading facilities exist for:

  • fertiliser
  • concentrates
  • bulk materials

Total throughput for the year ending 30 June 2002 was1 636 000 tonnes.

History

Townsville Port is the gateway to the North-west Minerals Province. MIM has been a major user and investor in the development of the Townsville Port for 70 years. With this investment came long term leases over strategic assets in the port. MIM utilises these assets to service the export of our products as well as that of third parties.

History

The Bowen Coke Works was established by the Queensland State Government in 1933 to utilise coking coal from the State Coal Mine in Collinsville. By 1975, MIM had taken over coal mining operations at Collinsville and in 1988 purchased and took over operation of the coke works.
