Barberton Tailings Reclamation Plant. Pan African’s riches. 3SMedia Mar 4, 2013. The saying, ‘one man’s rags are another man’s riches’ couldn’t be more true for precious metals producer Pan African Resources. Its acquisition of Harmony Gold subsidiary Evander Gold Mines, now unconditional, is the perfect example, writes Laura Read More. Pan African Resources CEO hands over the
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
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
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.

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
Tailings and mine waste '98 : proceedings of the Fifth International Conference on Tailings and Mine Waste '98, Fort Collins, Colorado, USA, 26 28 January 1998 (English)
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
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. TENORM: Copper Mining and
Title: The reclamation of Sullivan mine iron tailings: Creator: Ames, Susan Eveline: Date Issued: 1981: Description: The Sullivan Mine iron tailings pose serious problems to reclamation which result from their high acid producing potential, extreme saline conditions, relatively high concentrations of heavy metals and tendency to cement upon oxidation.

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
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
The tailings are a silt with 95 percent less than the 200 mesh and only 5 percent less than 0.008 mm. Particle SG is 4.2. Tests done on the tailings were trafficability cone tests, ring shear
