Tailings Management

ATC Williams has built an international reputation encompassing a lifecycle approach to the management of mine tailings, from initial development to closure and post closure performance. A holistic approach is critical to the delivery of safe, sustainable, and efficient solutions that meet the needs of our mining clients.

Understanding the characteristics and behaviour of tailings as it relates to effective management through the life of the containment facility demands a range of skills that has been the focus of ATC Williams over our 40-year history.

The company is actively involved in continued research into tailings behaviour, primarily through support of post-graduate studies supervised by world-class scholars.
