Gold Fields has set a target to maintain general landfill waste mass (non-hazardous waste other than tailings and waste rock) at 2015 levels of 11.2Mt, by ensuring a reduction in the waste that reaches landfill through greater use of on-site waste separation and recycling.

 — Given the high impact of traditional mining, the recovery of rare earth elements (REEs) from hazardous waste materials could become an option for the future in accordance with the principles of the circular economy. In this work, the technical feasibility of REEs recovery from metal mine tailings has been explored using electrokinetic …

 — The accumulation of gold mine tailings poses an environmental challenge. The feasibility of reusing this waste to fill underground mines was investigated. The tailings were mixed with Portland cement and water using a one-step method. The fluidity, bleeding rate, setting time, mechanical behavior, water quality analysis, and toxicity …

 — The future trends of mine tailings' recycling and reuse should relate to technological innovation development. The targeted valorization approaches should …

 — This study proposes a cleaner chlorine for effective utilization of cyanide tailings. • Thermodynamic analyses reveal that the theoretical best chlorine source is CaCl 2.. The rate of gold recovery was 85.99% by using CaCl 2.. CaCl 2 is the most environmentally friendly in regard to pollution.. CaCl 2 is the best chlorine source for …

 — This paper describes the mineralogical properties of gold tailings, including chemical composition, phase composition, particle size distribution, and microstructure; summarizes the recycling and utilization of components such as mica, feldspar, and valuable metals in gold tailings; reviews harmless treatment measures for harmful …

 — The type of extraction method that can be used on mine waste depends on the mineral deposits the tailings come from and what processing approach was used to generate them, says Jowitt. If similarities are found between systems, similar approaches could be used across tailings facilities.

Responsible Tailings Management & Dam Safety ... In 2023, independent reviews of our Carlin-Goldstrike, Carlin-Gold Quarry, Lumwana, Pueblo Viejo, Turquoise Ridge, Giant Nickel, Grants, El Indio, and Tambo TSFs were undertaken in line with our standard and GISTM requirements. ... reuse and recycle. Non-processing waste We track the volumes …

 — Targeting extraction from mine tailings waste, and cleaning it up in the process, therefore has the potential to be a win-win for locals, governments and mining companies. For the latter, not just from an …

 — Traditional gold tailings are mostly stored up to tailing ponds, which have problems such as waste of resources, large area occupation, environmental pollution and hidden safety hazards. With the ...

 — The mining industry produces billions of tons of mine tailings annually. However, because of their lack of economic value, most of the tailings are discarded near the mining sites, typically under water. The primary environmental concerns of mine tailings are related to their heavy metal and sulfidic mineral content. Oxidation of sulfidic …

 — Gold mine tailing, red mud and waste limestone cause very serious problems to the environment. Due to their abundant amount of waste as well as difficulties with disposal, an appropriate recycling ...

 — Visualizing the Size of Mine Tailings. On January 25th, 2019, a 10-meter tall wave traveling 120 km/h, washed 10 million m 3 of mining waste from the Brumadinho tailings dam over the Brazilian countryside killing somewhere between 270 and 320 people.. This was a manmade disaster, made from mining the materials we use daily. Every …

Tailings is an area of mining where the industry is constantly seeking new approaches and ideas. They are an inevitable byproduct of the mining process but require extensive management to protect people and the environment. ...
