The mine tailings near Taltal contained considerable amounts of copper (∼5000 ppm) and cobalt (∼115 ppm). After adaptation of the mesophilic consortium, 38% of Co and 86% of Cu were recovered in 2-L STR at 10% solid load after 12 days bioleaching at 30 °C. In a mini-pilot test in 20-L STR at 15% solid load, Co and Cu extraction reached …

A secondary cleaner flotation tailing sample containing Ni and Co obtained from a nickel flotation plant (Western Australia) was used in this study. The nickel is …
The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity ... The final tailing is constituted of the pre- (Kime et al. 2015). Therefore, the trade-off ...
Copper (80%) and cobalt (76%) are mainly distributed in fine solids of tailings. It is obvious that the flotation of the bearing particles of copper and cobalt will be influenced by their size distribution in the studied tailings. Nearly 35% tailings consist of particles with the size comprised between 400 and 68 meshes.
The influence of bacterial inoculation, pH, nutrient medium type and pulp density on the recovery of copper, nickel and cobalt from the tailing was investigated. The results showed that 55.0% of copper, 98.2% of nickel and 59.5% of cobalt could be extracted from the tailing through the bioleaching process after 30 days at 5% (w/v) pulp …
Cobalt is generally not obtained during smelting in pyrometallurgical processes and remains in the slag. Therefore, the recovery of cobalt from flotation tailings [12–14] or …
The sample consisted of 93–94% non-metallic and 5–7% metallic components, with 0.5192% copper, of which 93.64% was oxidized. Initially, a flotation process recovered 0.489% copper. Subsequently, an agitated acid leaching process assessed the effects of acid concentration, temperature, and time.
The treatment of complex silver cobalt ores occurring with antimony and arsenic require special metallurgical processing to produce concentrates most advantageous for smelting. Gravity concentration is …
The tailings from flotation contain most of the cobalt and hence it was reduced with coal and subjected to magnetic separation . The magnetic fraction was analysed for Cu, Co, Fe and Si and the results are shown in Table 3. It can be observed from Table 3 that copper and cobalt in the flotation tailing was upgraded to about 20 …
In this study, a hydrometallurgical method for the recovery of copper, cobalt, and zinc from copper slag flotation tailings (SFT) was investigated. SFT contains large amounts of …
The test coal samples for coal flotation tailing were obtained from the Zaozhuang mining area, Shandong province, China. The size distribution of the coal samples is given in Table 1. As observed, the ash content increased with the decrease of coal particle size. The size fraction of -0.045 mm with a high ash content of 64.42% occupied the ...
