NICKEL AND COBALT ORES: FLOTATION

2016-6-7  erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts for as much as 60% of the reagent cost incurred in the plant. Developments in Flotation

Flotation of mixed oxide sulphide copper-cobalt

2019-7-1  The grade–recovery curves for cobalt in the sulphide flotation stage are shown in Fig. 9-A. Dithiophosphate collector DF245 allows for the highest overall cobalt content in the sulphide concentrate, which decreases from 4600 to 3800 ppm in the flotation process. This again confirms the selectivity of a dithiophosphate structure.

Bioleaching of cobalt from Cu/Co-rich sulfidic mine

2020-11-1  Bioleaching tests with a tailings flotation concentrate (Co 0.06%; Cu 0.57%) showed a recovery of 66% cobalt and 33% copper. In addition, mineralogical analysis showed that cobalt occurred on the surface of framboidal pyrite and was mainly leached by microbial attack.

Copper-Cobalt ores Danafloat

Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt

2021-1-26  This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit. Separation flotation utilizes pneumatic and mechanical agitation to produce air bubbles that carry the mineral particles to the surface. Different reagents are used to attract the cobalt minerals to the bubbles in preference to copper.

Continuous Flotation Testing To Recover Cobalt From

During beneficiation, the cobalt is distributed to the various mill product streams as shown in figure 3. The run­ of-mine ore contains 0.015 wt pct Co. About 30 pct of this cobalt reports to the copper concentrate at an average grade of 0.50 wt pct Co. This represents an improvement ratio of 33.

2011-7-5  The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered e.g. the Kolwezi Tailings Project.

2018-6-9  Extraction of cobalt from complex ore flotation concentrates obtained from the Blackbird Mine. Idaho. USA is reviewed. After flotation of a primary copper concentrate, a bulk concentrate is recovered containing major amounts of cobalt, arsenic, and iron, with minor amounts of copper and nickel.
