1.0 Bayer Process 1.1 Introduction The Worsley Alumina refinery uses a modified Bayer Process to extract alumina from bauxite. Bauxite is ore which consists of gibbsite, boehmite, diaspore (which are minerals with elements of aluminium) and other minerals such as goethite and hematite. The manufacture of aluminium metal begins with the Bayer ...

The Worsley alumina refinery uses the Bayer process to produce metallurgical grade alumina, which is used as feedstock for aluminium smelting. Power and steam needed for the refinery are provided by a joint venture-owned onsite coal power station and a non-joint venture-owned on-site gas fired steam power generation plant.

Worsley Alumina is one of the largest bauxite mining and alumina refining operations in the world. Bauxite mining takes place near Boddington, 130km south-east of Perth. The bauxite is transported 51km by overland conveyor to our alumina refinery, 15km north-west of Collie, where the red rock is turned into white alumina powder using the Bayer ...

South32 Worsley Alumina is an integrated bauxite mining and alumina refining operation in the South West of Western Australia with a proud track record spanning more than 35 years. The Worsley Mine Development is the next phase of bauxite mining near Boddington, providing access to future reserves and resources to sustain production at our Worsley

Worsley Alumina refinery was commissioned in 1984 with a rated capacity of 1 million tonnes of alumina and like all modern refineries uses the Bayer process. Annual production in December 1999 had increased to approximately 1.9 million tonnes with a further increase to 3.1 million tonnes achieved by May 2001.

Mining and Refining – Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to ...

Worsley Alumina Pty Ltd Internship Program Final Thesis Report Paul Regan Page: 4 Acknowledgements From the moment I stepped onto the site at Worsley Alumina, I felt at home. The team in the process control group were quick to dispense with awkwardness with many jokes and invitations to outings given.

At the time, building the mine, conveyor belt and processing plant was Australia's most expensive capital project, costing AUD$1.2 billion and employing 3500 people. Over the past three decades our production has increased four-fold, making Worsley Alumina one of the largest and lowest-cost alumina producers in the world.

Worsley Alumina has been operating since 1984 and we celebrated our 35th anniversary in 2019. The Worsley Mine Development is the next phase of bauxite mining, providing access to future reserves and resources to sustain production at our Worsley Alumina refinery near Collie. The Worsley Mine Development includes three main components:

1 Worsley Alumina, Collie, Western Australia 2 BHP Billiton Bauxite and Alumina Technology, Netherlands Abstract The BRAHMA ("BHP-Billiton Refinery Alumina Hydrate Model Analysis") precipitation simulation model is used extensively at the Worsley Alumina Refinery as a tool to assist in controlling the precipitation process.

Automation Projects (built on Lean Six Sigma methods), alumina-proven lifecycle simulation, virtual engineering and Experion DCS have helped to compress schedules and reduced engineering by thousands of hours. This has been recognised through the Australian Engineers Excellence Award for the Worsley Alumina Upgrade project.

EXISTING WAGERUP REFINERY 4.1 ALUMINA REFINING PROCESS As with the majority of other commercial alumina refineries throughout the world, the Wagerup refinery uses the Bayer process to refine alumina from bauxite ore. This involves a number of key steps, including:

Worsley Alumina commenced commissioning of a Liquor Burner at their site near Collie in Western Australia in 2000. The Liquor Burner process removes organic contaminants in the caustic soda liquor used in the refining process, and involves a number of key process stages, including a …
