The strategic implementation of a thickened tailings system for an existing conventional TSF can be beneficial in terms of significantly reducing the required post-operational earthworks and the time to achieve final closure.

One of the most challenging aspects of the successful closure Read more... about Thickened Tailings Deposition for Closure

Uranium tailings are differentiated from other types of tailings due to the radioactive nature of the material.
Radioactive tailings facilities pose long term hazards relating to both exposure and dam failure, with the
principal concern being the potential harm to both operator and Read more... about Management of Uranium Tailings

Characterization of acid mine water by acidity helps us explore possibilities for recovering by-products with economic value and choosing the most suitable and efficient treatment system possible. This is because characterization by acidity allows us to ascertain not only protonic acidity, but Read more... about Acid Mine Water Treatment With Recovery Of By-Products Of Economic Value

Soil cover systems are routinely used to reduce acid rock drainage (ARD) from mine waste rock dumps and tailings impoundments. A technology for the analysis, design, instrumentation and monitoring of barrier-type (oxygen limiting) and store/release type covers has rapidly developed and the Read more... about The Integrity of Cover Systems - An Update

It is widely recognised that piezocone (CPTu) testing is a valuable technique for identifying the in situ engineering properties of tailings for use in stability and liquefaction assessments. Numerous empirical
procedures have been developed to relate the results
