These coarse tailings require no treatment before reclamation. Fluid tailings make up less than 10% of tailings and are treated and used for future reclamation into closure landscapes. Treating fluid tailings quickly and cost-effectively, as well as safely releasing water from our sites, is critical to improving our overall reclamation performance.

Thermal decomposition of ammonium sulphate. In order to better understand the process of thermochemical treatment of PGM tailings with (NH4)2SO4, it is important to gain insight on the thermal decomposition of pure (NH4)2SO4 over the temperature range studied since it will affect the thermochemical process.

Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it's important to reshape tailings management and accelerate the positive change.

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...
