The tailings at Gango contain substantial amount of gold with 7.37 g/t and 7.38 g/t at the surface and at 1m deep, respectively. Empirical data revealed that thiosulfate is a good lixiviantThe aim of this study was to develop a comprehensive technology for the utilization of tailings from quartz vein-hosted gold deposits. We investigated the recovery potential and separation process Comprehensive Utilization of Tailings in Quartz

Las Lagunas Gold Tailings Project Mining Technology
Las Lagunas Gold Tailings is a retreatment project involving the reprocessing of previously unrecovered gold and silver refractory tailings from the Pueblo Viejo mine. The project is situated 100km north-west of Santo Domingo, the capital city of Dominican Republic, in the Caribbean.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? Miners Make Money Reprocessing Tailings

Estimating processing cost for the recovery of valuable
1. Introduction. Nowadays, the mining industry faces great economic, social, and environmental challenges (Moran et al., 2014).The major issues are water scarcity, energy supply, decrease in the ore grade, and generation and disposal of waste (Marín et al., 2020).The mining industry is the largest waste producer worldwide, 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 is a series of experiments carried out by an international group of scientists to produce approximately 30 years of passive carbonation of mine tailings New Tailings Reprocessing Technology Has Environmental Benefits

Mine tailings: reprocess, recover & recycle The Intelligent
Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an Increasing population levels, growing economies, rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals, leading to growing concerns regarding their availability and the global efficiency of the mine supply chain.

In a response to the European Innovation Partnership (EIPs) “call to arms,” the European training network (H2020 MSCA ITN) for the remediation and reprocessing of sulfidic mining waste sites (SULTAN) was set up (https://etn-sultan.eu/).The objective of SULTAN is twofold, i.e., (1) mitigating environmental risks intrinsic to sulfidic tailings, and High temperature smelting with additives to dissolve Au from the gold concentrate into a molten copper was used in the research.

A review of circular economy strategies for mine tailings
5. Tailings management within the circular economy in mining. In this chapter, the possibilities to manage the mine tailings with reduce, reprocessing, upcycle, downcycle and disposal strategies are discussed. In the subchapter 5.2, an inventory of the metal content of mine tailings in Finland is presented. 5.1.With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing virgin material.How to generate value from tailings with reprocessing to be

Management of wastes from uranium mines and mills
The tailings slurry is pumped to a waste-retention system where the solids settle out and accumulate. In a few locations the ore is processed without fine grinding, and the resultant tailings are transported in a nearly dry form to a waste disposal area. The specific radioactivity of uranium mill tailings is low.WHITEHALL, Mont., Feb. 11, 2022 (GLOBE NEWSWIRE) -- Barrick Gold Corporation (NYSE:GOLD) (TSX:ABX) The pioneering Tailings Reprocessing Project at Barrick’s end-of-life Golden Sunlight MineGolden Sunlight’s Tailings Reprocessing Project a Model for

Tailings are what is left over after mills separate the metal from the mined rock. The processed material “tailings” comes from the “tail” end of a mining mill and comprise fine particles mixed with water forming a slurry. Mining companies will store this waste in dams or ponds.All of the World's Mine Tailings, in One Visualization
