Tailings dewatering | Weir Group

Nov 18, 2019· When tailings are not properly managed, the results can be lethal. It is vital that mine operators have a clear understanding of key risks and considerations related to this process, in particular, tailings dewatering. Every mine site is different and subject to varying environmental, regulatory, capital and operating cost constraints.

Introduction. Unreclaimed mine tailings represent an important environmental problem as aeolian dispersion and water erosion may transfer potentially toxic elements into local trophic webs and nearby human settlements (Mendez & Maier, 2008).Phytostabilization is a form of remediation that involves the use of plants for in-situ stabilization of tailings and contaminants (Mendez & Maier, 2008).

Phytoremediation of mine tailings in temperate and arid ...

Dec 01, 2007· Whether phytoextraction or phytostabilization is the goal, plants used need to be suited to the climate at the mine tailings site. In temperate regions tailings are often saturated or waterlogged and require plants adapted to slightly anaerobic and wetland conditions (Craw et al. 2007).In arid and semi-arid regions plants must be both drought- and salt-tolerant to tolerate dry, saline tailings ...
