Alfa Laval decanters revolutionize coal mine tailings management strategy
Rix’s Creek Coal Preparation Plant, Australia
DATE 2566-11-28The Rix’s Creek coal mining operation, part of the Bloomfield Group, set out to improve its onsite coal tailings management as part of its sustainability strategy to reduce water and energy consumption and minimize the surface footprint of waste handling processes.
After evaluating various technologies, Rix’s Creek engineers installed an Alfa Laval decanter centrifuge to dry coal tailings.
The result? Savings in capital expenditures as well as, about 90% recovery and re-use of the process water.
An Alfa Laval decanter centrifuge dewaters Rix’s Creek coal mine tailings, reducing the need for tailings dams while reducing capital investment and water and energy consumption.
Leading the industry in sustainable tailings management
