Tailings management in gold plants ScienceDirect
The tailings management system of a mining operation is comprised of many components which include: tailings treatment in the mill; slurry thickening; slurry The tailings stored underground as cemented paste backfill positively affect sustainable mining by both providing ground support and eliminating tailings in mines. The integrated paste technology (for both backfill and storage purposes) used for tailings disposal is considered by the EU Commission as one of the best available Recent practices in mine tailings’ recycling and reuse

Tailings storage facilities for tailings management Barr
Owners of tailings storage facilities and their engineers, along with the mining industry as a whole, must be dedicated to continued education and ongoing research to develop engineering tools and methodologies that are tailored to the unique nature of tailings. For geotechnical engineers, who are responsible for the stability of For more than 30 years, sulfide gold ores were treated in metallurgic plants located in Nova Lima, Minas Gerais, Brazil, and accumulated in the Cocoruto tailings dam.

Waste Management in the Gold and Silver Industry
Figure 6.4 combines the data on waste rock and tailings shown in Figs. 6.1 and 6.3, respectively, and shows the amount of total waste generated for Barrick operations between 2013 and 2016.Table 6.4 shows total waste generated, gold production and total waste generated per unit gold production. Total waste generated per ounce of An important part of the overall mining plan is the conventional stripping and removal of up to 80 ft of overburden (the tailings from previous dredging operations) with front-end loaders and a(PDF) Buyanhulu Mine (Tanzania) Paste Tailings Facility: Relating

Physico-Chemical Characteristics of Tailings from Gango Gold
In terms of the economic aspect, the tailings contain substantial amount of gold (7.38 g Au/t) with significant economic value. It is estimated that the tailings pond at Gango Gold Mine containsWater Recovery and Tailings Disposal Improved With Paste Thickening. Traditionally, waste disposal has been an environmental challenge for mining. But now the industry has begun to embrace paste, or thickened tailings, as a way to address the challenge. Paste thickening is different than conventional thickening.Tailings Management With Paste Thickening

Characterization and environmental impact assessment of gold
In arid regions, thickened tailings and paste technology methods are usually applied in disposal process. The benefits of this method include high water recovery, size reduction of the impoundment, low dam failure risks and low environmental impacts as a result of preserved seepage from the stored paste tailings ( Williams and Seddon, An Experimental Study on the Hindered Settling Properties of Backfill Tailings Particles.

Deposition of gold mining tailings in tropical soils: metal
Purpose This study consists of the evaluation of metals acute toxicity levels taking into consideration a hypothetic scenario of dam breaking and land deposition of two different gold mining tailings, derived from flotation and cyanidation processes. From this assumption, mixtures of soil:tailings caused by a potential mining dam collapse The generation of tailings in the world today is immense, since only ounces or pounds of metals are extracted for each ton of ore processed. In 2022, it was estimated that more than 14 billion metric tons of mining tailings were produced per year in the world.

Filtered Dry Stacked Tailings-The Fundamentals ResearchGate
For example, mine tailings are often stored in large tailings storage facilities and may be deposited as dewatered paste, dry stacks, or slurries (Davies, 2011; Davies et al., 2010;Fourie, 2009In Peru, socio-environmental conflicts related to the development of mining-metallurgical processes and the responsible disposal of mine tailings have become central issues for accepting mining projects, especially regarding building relationships of trust with the communities.
