Mine tailings are fine-grained mineral waste produced during ore processing, and they contain valuable metals, water, and toxic elements that cause serious environmental concerns. The most common approach for tailing management is confinement in tailings storage facilities (TSFs) in the form of dams. Management of tailings dams is a challenge and many fatalities and environmental hazards have been recorded due to dam failures. Solid-liquid recovery of mine tailings is an excellent approach to improve mining operations' sustainability and circularity and ensure cleaner environments. Previous reviews focused on thickened tailings in China and Peru and some research tailored towards tailing dam construction, disaster, and management. Despite development in tailing management practice and technology improvement, a holistic review of innovative solid-liquid recovery of mine tailings towards tailings dam reduction is lacking. This paper presents the current state of the art in the solid-liquid recovery of mine tailings to reduce or eliminate tailing dams where possible. The paper presents methods and technologies for tailings dewatering for improved solid-liquid recovery and potential applications of tailings reuse in mining and construction industries for sustainability and circularity purposes.
