“…Recent developments suggest that improvements may be achieved with hydrocyclone units in smaller diameter (Yang, et al, 2013), or operated under modified process conditions, e.g., cyclic flow (Zhao, et al, 2008), and application of an electric field (Nenu, et al, 2010), though care must be taken to avoid underflow blockage for small units. Experimental work on utilizing these performance enhancements in hydrocyclone for treating fine mineral tailings slurry has yet been published at this time.…”

Highlights Presented facts on escalating generation of fine mineral tailings worldwide.  Overview of coal, alumina, oil sands, and base metals tailings characteristics.  Reviewed theoretical and industrial developments for tailings management.  Determined numerous knowledge gaps between current theories and practices.  Identified opportunities for improvement towards more sustainable practices. Graphical AbstractEvolution of fine mineral tailings treatment objectives.Figures "Flocculated solids" and "Stackable solids" are adopted from Alamgir, et al. (2012), permission pending. The last figure "Reclaimed land" is adopted from Golder Associates (2009), permission pending. AbstractThe mining industry produces fluid fine mineral tailings on the order of millions of tonnes each year, with billions of tonnes already stored globally. This trend is expected to escalate as demand for mineral products continues to grow with increasingly lower grade ores being more commonly exploited by hydrometallurgy. Ubiquitous presence and enrichment of fine solids such as silt and clays in fluid fine mineral tailings prevent efficient solid-liquid separation and timely re-use of valuable process water. Long-term storage of such fluid waste materials not only incurs a huge operating cost, but also creates substantial environmental liabilities of tailings ponds for mining operators. This review broadly examines current theoretical understandings and prevalent industrial practices on treating fine mineral tailings for greater water recovery and reduced environmental footprint of mining operations.
