Flotation experiments were conducted to investigate the effect of pH and pH conditioning time, and experimental conditions are provided in Table 4. Figure 5shows that pH had a significant effect on both the Co grade and recovery. The optimal Co grade and recovery values were …
Tailings are residual material streams generated in mining activities. Regarding sulfide ore mines, tailings are typically produced in froth flotation process, where valuable sulfide minerals are selectively separated from non-valuable gangue (Fuerstenau et al., 2007).After the separation, gangue minerals are disposed in tailing ponds (Lottermosser, 2010).
In this study, iron- and sulfur-oxidizing microorganisms were utilized in bioleaching to treat pyrite-rich tailings to liberate mainly cobalt, alongside with other valuable metals.
For example, when flotation was applied to cobalt-containing tailings from Sivas-Divrigi iron ore concentrator in Turkey (Sirkeci et al., 2006) and flotation tailings of oxidized ores of copper ...

The roughing flotation of tailings was achieved at laboratory (14 min) using a Denver D-12 mechanical machine with the impeller speed kept at 1350 rpm (Fig. 3).The yields in copper and cobalt were studied versus the reagents dosage. The reagents were introduced in the slurry to be floated while keeping constant (0.1) the ratio of dosages.

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
The time-dependent recovery of cobalt during the sulphide flotation stage is shown in Fig. 7-A. Cobalt recovery is relatively low for all collectors, with a maximum recovery of 31% cobalt for the stronger thiocarbamate collector (DF507B) and a minimum of 24% for DF068. The phosphorodithioate-MBT collector (DF571) returns a better performance ...
