Name of the project and location Gregory Crinum coal-mine upgrade, Queensland, Australia.

Project description The project will involve the upgrade of the coal-processing plant's flotation circuit at the Gregory Crinum coal-mine.

The yield of coking coal at the mine's coal-processing plant will be increased by more than 6% by replacing the existing conventional circuit with new flotation technology. This will result in a higher-density wash in the main processing plant, leading to an increased tonnage of the coking coal produced.

A clean-coal thickener will also be installed to assist with dewatering and control of the feed density to the existing belt-filter units.

Value A$24-million.

Duration The project started in November 2005 and is scheduled for completion at the end of 2006.

Breakdown of main contracts Bateman Engineering has been awarded the contract for the upgrade, which will be undertaken form the company's Brisbane office.

Client BHP Billiton Mitsubishi Alliance (BMA).
