Mine tailings (MTs) are the finely ground residuals after the valuable metals have been extracted from the ore beneficiation process. Mineral processing of the ore continuously produces a significant amount of MTs in their various processed phases (e.g., solid, slurry). ... Because of the insufficient geopolymerization and the crushing ...
With lower grade ores and the possibility of more extreme weather events associated with global climate change, the industry must address the rising concerns …
Mine tailings from gold mines lead to the accumulation of heavy metals, acid rock drainage, dust emission, and surface runoff, with considerable effects on …
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 …
The mine tailings can be considered for re-mining, instead of being merely discarded. Re-mining tailings extends the operating life of existing mines. The approach of viewing the disused materials from mines (overburden and tailings) as a potential resource rather than waste helps to ascertain strategies for preventing waste or transforming ...

Higher capacity up front crushing circuit optimizes Stage 2 expansion constructability: ... (C$456 million), mining costs (C$63 million) and tailings management (C$137 million). Sustaining capital is estimated to average C$57 million per year for years 1-5, C$50 million per year in phase 2 and C$37 million per year in phase 3. Mobile fleet ...
Two of the most notable failures in the past decade took place at iron ore mine sites in Brazil. In 2015, a tailings dam breach at the Germano mine killed 19 people and polluted 650 kilometres of the Doce River, impacting thousands of livelihoods. In 2019, the collapse of the Córrego do Feijão tailings dam killed 272 people.
