Filtered Dry Stack Tailings: The 'State of Play' For High ...

ABSTRACT. Tailings storage facilities are generally the most significant environmental liability for mine permitting operation and closure. Tailings filtration and “dry-stacking” reduces the risk of liquefaction improves rehabilitation and minimises water consumption compared to conventional wet impoundments and is therefore considered to be environmental best practice for tailings ...

Tailing Disposal - an overview | ScienceDirect Topics

After settling and self-weight consolidation the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings the dry density is about 1.8 tm 3 due to their low G s while for metalliferous tailings the dry density is up to 1.5 tm 3 due to their higher G s. Figures 2.4a and b show typical wet and dry density and w profiles with depth for ...
