·Historically safe containment has been the main goal of tailings management Disposal has taken place in sizable surface impoundments that are enclosed by dams or embankments as well as in subterranean workings and unnatural depressions [10] [11] However the environment and communities are seriously endangered by the inappropriate management
such as mine tailings are happened About 5 billion tons of tailings are discharged a year all over the world [2] On the other hand the content of useful components especially copper and precious metals in the tailings is few times higher than the primary copper ores Therefore mine tailings present a very important
·Recovery of valuable elements from mine tailings W Flores1 H Contreras2 P Garrido3 J Concha4 y P Espinoza5 1 Centro de Investigación CI JRI Chile Project engineer wflores and 56 22 361 8550 mining tailings Depending on the characteristics of each of these tailings elements that can feasibly be recovered such as

·Mining is an important industry accounting for % 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 2025 Adding to this the
·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 accounting for between 5 and 7 billion tons per year only
·Tailings recycling refers to recovering valuable materials from mine tailings which are the by products generated during the extraction of minerals from ore Instead of allowing these tailings to be disposed of as waste recycling involves reprocessing them to extract any remaining valuable minerals
·Approximately 12 million tonnes of tailings are stored in two ponds at the mine Kettle River noted in a news release that the tailings do not conform to 43 101 standards but historical reports indicate gold values of between and g/t The former mine treated ore with a % Cu and g/t Au grade It s gold recovery was in the 65% range
·Key points The business will acquire gold mine tailings dumps test samples to determine assay and recoverability then place processing equipment on approved dumps to recover gold Products are gold recovery operations on mine dumps in Zimbabwe and other gold rich African areas where competition is currently limited
·The increasing global demand for critical minerals driven by rapid population growth and the widespread adoption of low carbon technologies electric vehicles and clean energy systems highlights the urgent need for sustainable resource management Mine tailings traditionally considered waste are now being recognized as valuable secondary sources for
