Coal preparation

Alfa Laval is revolutionising the treatment and disposal of coal tailings. This is being led by a strong Australian demand to look after the environment: to conserve water and make tailings dams a thing of the past.

Taking our proven expertise for creating decanters that work in the toughest of mining conditions, coal tailings are moved through Alfa Laval's next generation of decanters via solid bowl dewatering. This process extracts and retains the water within the system, while producing a solid cake that is then used to help with mine rehabilitation.

Main advantages of Alfa Laval’s solution for coal washeries include excellent separation, minimal operator monitoring, significantly lower capital costs, lower maintenance and operational costs than other technologies to produce a comparable result.
