Processing of materials that originated from tailings industrial plants (with a wide range particle size distribution, “PSD”) without grinding has several advantages since mines are faced with lot pressure to minimize their environmental impacts. This article indicates the introduction submicron bubbles (known as nanobubbles, “NBs”) conventional flotation could improve separation efficiency val...

To increase resource efficiency, mining residues–especially tailings–have come into the focus of research, companies, and politics. Tailings still contain varying amounts unextracted elements value minerals that were not economic interest during production. As for primary mineral deposits, only a small share tailings offers possibility an reprocessing. minimize exploration expenditure, stepwise...

Copper and cobalt demand is projected to be increased from here 2050 the challenge find treat economically minerals which contains those metals. Several tailings oxide ores throughout word contain good grades of copper that should recovered by froth flotation. This paper investigates recovery through reprocessing spiral classifier determination specific reagents dosage. The flotation behaviours...

During the Late Permian period, coal from Jiashun Mine in Xingren City, Guizhou Province, China, is characterized by a high sulfur (5.84%) and lithium (Li) (94.5 μg/g) content. Lithium critical metal context of global energy transition. Considering importance environmental protection resource utilization, mode occurrence distribution trace elements different preparation products were investigat...

Companhia Brasileira de Alumínio (CBA) has bauxite processing plants at Poços de Caldas and Itamarati de Minas, and a new processing plant at Miraí that has been operating since June, 2008; all of them are in the State of Minas Gerais. The plants haveunits for the crushing, scrubbing and screening operations. The screened oversize is the concentrate or washed bauxite. At Itamarati de Minas, the...

The RTH flotation tailing dump, located in the old open pit Bor about 500 m southeast of Flotation Plant, has been continuous operational work since 1985. flotations dumps are important mining facilities that constantly changed during their exploitation period. Due to changes occurring dump its exploitation, it is necessary perform a technical and technological surveillance-auscultation order c...

In this research work, the zinc extraction was investigated, using bioleaching process from a low grade zinc concentrate which was produced from the accumulated flotation tailings. Zinc content was initially upgraded to 11.97% by flotation process. Bioleaching experiments were designed and carried out by a mixed culture of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans, Leptospir...
