This chapter provides an overview of mine tailings and mine tailings facilities. It illustrates why and how mine tailings are produced, and the complexity involved in the long-term storage and management of this waste product. The call for a global standard for mine tailings management is a response to recent catastrophic facility failures. Mining …

Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings …

A bar graph showing the gold concentration and mass percentages within each of the density-defined operational mineral fractions from the corresponding goldfield tailings dump material.

The tailings dam stores process effluent from the gold extraction plant. Wastewater samples taken from the tailings dam were analyzed for physico-chemical characteristics.

afety guidelines and good practices for tailings management facilities.Authorities, tailings management facility operators and the public are invited to apply these guidelines and good practices, which are intended to contribute to limiting the number of accidents at tailings management facilities and. he severity of their consequences.

The latter is a concern in the Witwatersrand goldfields of South Africa, where communities are located in close proximity to gold mining operations and/or both current and defunct tailings dumps.

At modern gold mines, more than 99.999% of the originally mined and processed ore may finally become tailings. The dry weight of tailings produced is nearly equal to the dry weight of the ore mined. The grain size of tailings is relatively restricted and ranges from clay to sand (i.e. 2 μm to 2 mm).

The research findings identified numerous potential uses for gold tailings including reusing gold mine tailings in making bricks, ceramics, cement additives, backfill, stone paper and aggregate material for construction. The derelict tailing dumps can also be used for recreation purposes, tourism and many other land use applications.

Based on these discussions, a new technology roadmap that combines multistage magnetic separation and cemented filling is proposed for the clean utilization …

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.

This paper describes the test work, process design of a processing system at the Mazowe Mine that will improve the extraction efficiency from gold tailings material. The recovery is derived from the separation of the gold contained within the sulphides of the tailings material and a dedicated process stream to recover that gold.

Hydro-mining will be utilised at the larger tailings dumps, using hydraulic guns cutting mine widths of 15 m wide and 20 m deep. Load-and-haul mining will be used to extract resources from the smaller North Sands and South Sands tailings dumps.

The tailings dumps originating from gold mining in South Africa's Witwatersrand still contain notable gold endowments. Most tailings reprocessing operations target a native gold fraction using re-milling and carbon-in-leach extraction; however, up to 50–70% of the remaining gold is still not recoverable and instead …

e life cycle of a tailings facility. This is a multidisciplinary process for building mining landforms, landscapes, and regions to meet agree -upon land use goals and objectives. The process ideally begins with the initial designs of tailings landforms (or in the case of most existing sites, are adopted midstream) and continu

Extraction of valuable metals from tailings dumps traditionally regarded as waste, has long been researched by …

This study explores the possibility of reclaiming the tailings dump of the Louis Moore Mine in the Giyani Greenstone Belt, investigates potential hazards to communities in the …

Tailings Retreatment: Mogale heads for year-end start-up. South African gold producer Pan African Resources, listed on London's AIM and the JSE, is on time and within budget on its US$135 million Mogale Tailings Retreatment (MTR) project at Mintails, which represents a major expansion of its tailings retreatment footprint.

The South African gold mining industry has a legacy of abundant tailings dams, which have attracted the attention of investors because of their potential as a cheaper secondary gold resource. In ...

Physicochemical properties, heavy metals, and metal-tolerant bacteria profiles of abandoned gold mine tailings in Krugersdorp, South Africa

Gold extraction is largely driven by mineralogical factors, which often cause gold losses to various tailings. Mineralogical factors affecting gold recovery include grain size and shape, surface coating or rimming on gold particles, the presence of cyanide or oxygen-consuming minerals or preg-robbers, the presence of slow-dissolving gold minerals and the …

The cyanide content of gold tailings exceeds the standard seriously due to the cyanide extraction process. In order to improve the resource utilization efficiency of gold tailings, a medium ...

Several efforts are underway to extract gold and copper from tailings. Reprocessing mine tailings may also have environmental benefits. A recent project described in Mining.com is a series of experiments carried out by an international group of scientists to produce approximately 30 years of passive carbonation of mine tailings …

Mine tailings, consisting of process effluents that are generated in a mineral processing plant, are generally transferred to tailings ponds/impoundments to meet environmental regulations and site-specific factors before discharge.

Most tailings reprocessing operations target a native gold fraction using re-milling and carbon-in-leach extraction; however, up to 50–70% of the remaining gold is …

100 TPD Modular Gold Tailings Plant, 4' x 10' ball mill, flotation cells, gold concentrator, & concentrating table. Equip yourself with the gold standard.

A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using required mineral processing solutions to liberate the valuable metals. The discarded tailings are then dewatered and dry stacked, and the water recycled within the plant or properly disposed back to nature.

The cyanide content of gold tailings exceeds the standard seriously due to the cyanide extraction process. In order to improve the resource utilization efficiency of gold tailings, a medium-temperature roasting experiment was carried out on the stock tailings of Paishanlou gold mine after washing and pressing filtration treatment.
