  • From Tailings to Treasure? Miners Make Money

    Tailing may turn out to be a viable source of another valuable and highly sought-after resource—rare earth elements. An article appearing on ABC News, Old Mine Tailings: New Mother Lode for Rare Elements,reported findings from the U.S. Geological Survey indicating that discarded mine tailings may yield significant amounts of rare earth elements; modern extraction techniques would now

  • WikiZero Oil sands tailings ponds (Canada)

    Oil sands tailings ponds are engineered dam and dyke systems used to capture oil sand tailings.Oil sand tailings contain a mixture of salts, suspended solids and other dissolvable chemical compounds such as acids, benzene, hydrocarbons residual bitumen, fine silts and water. Large volumes of tailings are a byproduct of bitumen extraction from the oil sands and managing these tailings is one of

  • Paste thickening optimizes tailings disposal and water

    By Jim McMahon. Mine tailings disposal, and its impact on water usage, is an important concern for any mining company. The challenge today, whether extracting aluminum, zinc, gold or iron ore, is how to dispose of tailings material such that it is contained and stable, while maximizing water reuse and minimizing surface footprint.

  • Golder’s Paste Team Celebrates 20 Years of Innovative

    Paste backfill technology involves the processing of by-products e.g. tailings, in on-site processing plants that Golder designs and builds, to produce a material that is used as structural fill to stabilize underground workings. Paste and thickened tailings for surface disposal developed out of the backfill science and is now widely used as one of the best available technologies for mine

  • liming introduces new mine tailings management

    Water conservation, efficient tailings management and responsible mine reclamation are becoming increasingly important for mines to ensure their license to operate. Spearheaded by the launch of the new liming VPX filter for tailings dewatering, liming introduces its comprehensive tailings management concept to enable and support environmentally and economically sustainable mining.

    University, Denmark *Correspondence: Tariq Siddique, Department of Renewable Resources, University of Alberta, 442-Earth Sciences Building, Edmonton, AB T6G 2E3, Canada e-mail: [email protected] Dispersed clay particles in mine tailings and soft sediments remain suspended for decades, hindering consolidation and challenging effective management of these

  • pper mine tailings centrifuge MC World

    Tailings Slurry pipelines are commonly used to transfer mine residue from the processing plant to the tailings storage facility. Historically these pipelines were designed to operate at low solids concentrations, however as dewatering technology improved and solids concentrations increased, residue disposal systems have become significantly more complex.

  • Microbially-accelerated consolidation of oil sands

    Any process that increases the settling of clay particles in oil sands tailings ponds will enhance consolidation of tailings to reduce the inventory volume and enable reclamation, and will increase recovery of porewater from MFT for re-use and reduction of fresh water demand; even marginal increases in consolidation translate into enormous volumes, given the scale of existing tailings ponds

  • Mining 2020 Laws and Regulations Canada ICLG

    For example, following the failure of a tailings storage facility in 2014, British Columbia updated its Health, Safety and Reclamation Code for Mines in British Columbia to require mines to develop and maintain a tailings management system that includes regular audits. Managers are required to retain an engineer of record to ensure that the mine’s tailings storage facility has been designed
