Reuse method for deposits of polymetallic tailings in a state of abandonment through the application of mineral flotation
(Springer Science and Business Media Deutschland GmbH, 2019-01-01)
In the mining industry, due to the extraction and processing of ore, a significant amount of tailings are produced which are discharged into deposits. In some cases, these are in contact with effluents and generate acid ...
Accounting for tailings dam failures in the valuation of mining projects.
The number of major tailings dam failures has doubled over the past 20 years, culminating in the tragic accident at Brumadinho in Brazil where about 300 people lost their lives. In this context, there is a growing demand ...
Advances in Mine Tailings and Water Management in the Mining Industry for a Circular Economy
(2020)
The mining industry consumes vast quantities of water and energy to produce a metal or mineral product from mineral resources on the earth’s crust, leaving an enormous amount of mining waste. The linear thinking of the ...
A Cyanide Tailings Management Method Using Pseudomonas Fluorescens to Improve Conventional Treatments for Progressive Closure at Small Gold Mines
(Springer, 2020-01-01)
Based on the review of different research studies, we could assess that, due to their unique biological features, microbes, specifically bacteria, could be used to repair damaged soils with heavy metal and toxic compound ...
Co-occurrence interaction networks of extremophile species living in a copper mining tailing
(Frontiers Media, 2022)
Copper mining tailings are characterized by high concentrations of heavy metals and an acidic pH, conditions that require an extreme adaptation for any organism. Currently, several bacterial species have been isolated and ...
Tracking cobalt, REE and gold from a porphyry-type deposit by LA-ICP-MS: a geological approach towards metal-selective mining in tailings
(MDPI, 2020)
High-resolution mineral characterization performed on mine material from a giant porphyry copper deposit shows that critical and precious metals, such as cobalt, lanthanum, gold, silver, and tellurium, are concentrated in ...
Characteristics of an iron-reducing, moderately acidophilic actinobacterium isolated from pyritic mine waste, and its potential role in mitigating mineral dissolution in mineral tailings deposits
(2020-07)
Reactive pyritic mine tailings can be populated by chemolithotrophic prokaryotes that enhance the solubilities of many metals, though iron-reducing heterotrophic microorganisms can inhibit the environmental risk posed by ...
