Tailings management has long been a concern in mineral processing operations, and recently has been brought back to our attention after multiple facility failures. In this month's blog, we look at how switching from a reactive to a proactive approach to tailings management can provide more long term economic, social and safety benefits.

Mining involves the processing of mined ore to separate valuable minerals, leaving behind huge volumes of waste tailings. Driven by mining volumes, globally generated tailings are estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron per annum. Water conservation and the cost of tailings and reclamation are also …

The process water bound by the tailings remains unused. With modern dewatering solutions, mining residues can be treated economically and the process water that they contain can be recovered. This saves both space and cost and is environmentally friendly. In mining, the term tailings refers to fine-grained residues in the form of sludges.
