Abstract

A process to treat fines tailings generated from mining operations, wherein tailings material is sprayed onto a solid substrate as a thin layer and allowed to dry. The spray may be re-applied on top of the dried tailings film leading to multiple layers of dried tailings solids. The method may yield a solid, dry, and consolidated tailings material.
