The Reprocessing and Revalorization of Critical Minerals
7 Citations Metrics Abstract Mine tailings, the byproduct of mining and mineral processing, are increasingly mass produced as a result of increased demand Due to growing mining volumes, global tailings generation was estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron in 2018. It is well known by the How to generate value from tailings with reprocessing to be

Process effluents and mine tailings: sources, effects and
Most mines produce tailings as the final waste from mining the ore body, ore processing, and recovering the valuable metals and minerals. Mine tailings are the residue that results from mining, In this context, the optimization of the process parameters is important to develop a process flowsheet for successful desulfurization of mine tailings to prevent Feasibility of reprocessing gold tailings: Integrated management

Minerals Free Full-Text Re-Thinking Mining Waste
Mining wastes, particularly in the form of waste rocks and tailings, can have major social and environmental impacts. There is a need for comprehensive long-term strategies for transforming the mining The advantage of re-processing of mine tailings for the recovery of valuable elements consists in the elimination of the mining, crushing, and milling involved in the processing of primary ores. The elimination of these stages considerably reduces the consumption of energy and water, and consequently diminishes CO 2 emissions ( Estimating processing cost for the recovery of valuable elements

Tailings Reprocessing: Benefits for Mining and Society
By reprocessing tailings, the mining sector can adopt new technologies, methods, and practices that can improve the efficiency, quality, and safety of mineral processing and recovery. TailingsMine tailings mining can contribute especially to the SDG11 “Sustainable Cities and Communities” and to the SDG12 “Responsible Consumption and Production” by minimizing the output of waste (World Economic Forum, 2016). Tailings valorization means the recovery of residual metals and utilization of the mineral matrix.Towards circular economy in mining: Opportunities and

Geosciences Free Full-Text Recycling and Reuse of Mine Tailings
Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. It reached 7 billion tonnes of mine tailings generated yearly worldwide, and 19 billion solid tailings will be accumulated by Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025. Goldfields has also developed new technology for a tailings retreatment plant, and processes 12,000 tons of From Tailings to Treasure? A New Mother Lode Thermo Fisher

Socio-Environmental Risks Linked with Mine Tailings Chemical
There is a need to define mine tailings in a clear, precise, multidisciplinary, transdisciplinary, and holistic manner, considering not only geotechnical and hydraulic concepts but also integrating environmental and geochemical aspects with implications for the sustainability of mining. This article corresponds to an independent This study introduces a framework to evaluate the economic risk related to the re-processing of mine tailings to obtain CRMs. The framework, based on real options analysis (ROA), and sensitivity and uncertainty analysis, was applied to analyze the profitability of using mine tailings as a source of CRMs in the Chilean mining industry.Geochemistry of a copper mine tailings deposit in Repparfjorden

Selective Process Route to Recover Magnetite from Springer
Copper mine operations consistently generate a large quantity of tailings after their concentration processing. These tailings are either piled up or stored in a dam, where both alternatives of disposal lead to environmental impacts. The dam copper tailings have a huge potential for by-product production thus improving sustainability and The extent to which useful substance is lost to tailings during ore processing determines whether or not a deposit can be economically exploited. Adjusted Cost Models and the Economies of Reprocessing Copper Mine Tailings in Chile’, Metals, vol. 11, no. 1, 2021, p. 103, DOI: 10.3390/met11010103, (accessed 26 May 2021).Copper tailings reprocessing Sciendo

MINE TAILINGS FACILITIES: OVERVIEW AND INDUSTRY TRENDS
2. MINE TAILINGS AND TAILINGS FACILITIES: AN OVERVIEW Mine tailings are the waste material that remains after the economic fraction has been extracted from the mineral ore. Tailings consist of a slurry of ground rock, and water and chemical reagents that remain after processing. The composition of mine tailings variesAccepting this, many of the reclamation and processing techniques may be applicable to the recovery of other minerals. For the purpose of this paper, gold mining residues with a particle size of approximately 70–80% finer than 74 μm are defined as slime and residues grading 10–20% finer than 74 μm as sand.
