Responding to challenges involved in meeting environmental obligations for tailings storage, global industry leader in fine particle management, Reynolds Soil Technologies (RST), has developed a range of services to treat and rehabilitate tailings dams.

RSTRST’s advanced crusting agents are being used by mine operations and power plants to control dust when the surface moisture in tailings dams is evaporated or recycled, with fine particles from the remaining dry waste becoming airborne if untreated.

Hydroseeding and hydromulching technologies developed by RST are also being utilised for the long-term rehabilitation of tailings dams to support revegetation of the land that is no longer in use.

With environmental requirements becoming more rigorous, companies responsible for the management of tailings dams are looking to RST for practical and affordable solutions that meet high standards and minimise the use of excessive water.

RST Operations and Technical Director David Handel said his team provided short- and long-term solutions to assist major mines and power plants reduce the risk and meet environmental obligations for dust control on some very large tailings dams both in Australia and overseas.

Handel noted that there currently is no cost alternative to crusting for the suppression of dust, other than revegetation, which was the long-term goal for companies managing tailings dams.
