· Water reduction and footprints of tailing facilities can be achieved with 's Ecotails tailings solution – a game changing opportunity for the mining sector. "The large footprint of conventional tailings dams is a key issue for many mines, as dilute tailings usually take up a large surface area of a mine's property," says Leonard Neluvhola, regional product line manager ...
Mining is one of the main economic activities of several developing countries as Chile. Due to the progressive fall of the ore grades and the increasingly refractory composition of minerals, concentrating plants have increased that has led to an increase in the generation of tailings. Tailings, especially those obtained in the past, have remaining copper and other valuable species in ...
The disposal of tailings is commonly identified as the single most important source of environmental impact for many mining operations (Vick 1990). This is not surprising when considering that the volume of tailings requiring storage can often exceed the insitu total volume of the ore being mined and processed. Over the last century the volumes of tailings being generated has grown ...

19/08/2020 · An open pit mine in subSaharan Africa is operating in a jurisdiction where relations are tense, there is artisanal mining and water is always an issue. The tailings dam seems sound for the moment but may become an issue in the years to come. Communities live downstream from both the pit and tailings dam, and allegations of pollution are routine.
recover copper as a saleable product and minimize the amount of copper reporting as metal sludge to the tailings dam. The technologies considered included lime neutralisation, reverse osmosis, conventional SX–EW, sulphide precipitation, ELSA cementation, ion exchange (IX), and the EMEW process. This paper outlines the basis of the IX process, discusses reasons for its preference as the .
· Several efforts are underway to extract gold and copper from tailings. Reprocessing mine tailings may also have environmental benefits. A recent project described in is a series of experiments carried out by an international group of scientists to produce approximately 30 years of passive carbonation of mine tailings within four weeks. In a paper published in the journal Economic ...
Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from lowgrade ores is the most important industrial appliion and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.
The present study focused on the reprocessing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.
Treatment of mining wastewater, including tailings and acid mine drainage treatment solutions Ultrafiltration technology already plays an important part in many mining operations across the globe, both in producing water to the required specifiions, and .
Towards Greener Lixiviants in Value Recovery from Mine Wastes: Efficacy of Organic Acids for the Dissolution of Copper and Arsenic from Legacy Mine Tailings Richard A. Crane 1,* and Devin J. Sapsford 2 1 Camborne School of Mines, College of Engineering, Mathematics and .
Hydrophobicity in Copper Tailings. Expande is inviting companies to prequalify for the Hydrophobicity in Copper Tailings challenge by 7 September 2021. Mining company: BHP Technological solutions are sought to adjust the physical properties of the solid contained in the tailings to repel water, that is, to increase its hydrophobicity. The final ...
· Insitu recovery is a rarer method than regular copper mining, as the minerals must be in soluble form and loed below the water table, while the ground must be permeable to allow fluid to pass ...
Jul 22, 2020 · This work aimed to investigate optimal leaching technology for copper extraction from old flotation tailings of the Copper Mine Bor. The leaching degree of copper after leaching with sulphuric acid at 80 °C was 50%, the maximal leaching degree was achieved after 30 minutes. Then, old flotation tailings were leached with adapted moderately thermophilic acidophilic bacteria in a bioreactor at ...
