Nickel ores are critical feedstock materials currently used in the industrial production of batteries and alloys, as well as in aviation. (Reeks et al., 2020).Nickel sulfide minerals are a primary nickel source for industrial beneficiation, in which froth flotation is the main method employed (Liu et al., 2018a; Yu et al., 2019; Peng et al., 2020).

flotation, separation is found to improve with increase in collector concentration and pH, as indicated by the decrease in retention ratio for Ti02 in combined clay product as well as the increase in the co-efficient of separation.

The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up.

In separation experiments with soil mixtures, clay- and silt-sized fine particles that had been attached to HPOS NPs were separated by flotation due to gravity, and the separation efficiency ...

In the two mineral flotation separation tests, reverse flotation had better selectivity for coarse-grained minerals. The maximum separation efficiency of the mixed ore with a particle size of 0.125–0.075 mm was 71.88%, the recovery of kaolinite in the concentrate was 84.97%, and the recovery of quartz amounted to 13.10%.

In the present study, an amine polyethoxylated surfactant was used as a bifunctional surfactant that collected clay particles and acted as a ing agent in the flotation process. The pH conditions strongly affected the …

The separation of LRC through flotation is an enormous challenge due to the high concentration of oxygenated functional groups on the coal surface, which leads to low recovery rates. Hence, we focused on examining the effect of quartz, kaolinite, montmorillonite, and chlorite on the recovery of LRC during flotation. ... The extended DLVO ...

Lithium-bearing clays have been identified as future lithium sources; in particular, after hectorite-type clay was concerned due to its large potential size (Meshram et al., 2014; Castor and Henry, 2020).Hectorite, a clay mineral found in Hector, California, that contains approximately 0.5% lithium, was found to be similar to the original saponite (Foshag and …

In this study, the feasibility of using a clay binder as slime depressant for phosphate flotation was investigated by conducting batch mechanical flotation tests using a 16-200 mesh phosphate sample under various operating conditions.

The main methods for the separation are flotation and dense medium separation. The main method for minerals phase transfer is roasting. Since the percentage of clay-type lithium resources is less in the past, the research on the development and utilization of it is limited, especially for the research of concentration.

industry, and the difficulty of flotation separation mainly depends on the unique interface characteristics between coal and gangue minerals (Yu et al., 2017). Froth flotation is a technology that separates particles based on their selective adhesion to air ... To mitigate the detrimental effects of clay minerals on mineral flotation, colloidal ...

Ion flotation involves separation of ions capable of association with a surfactant from other ions, molecular matter, or waste material from aqueous solutions. In this case, equimolar amounts of surface-active agents

Among the influencing factors shown in Fig. 1, particle size is the most important [[9], [10], [11]].Froth flotation works best when minerals are in an intermediate particle size range, typically from 20 to 150 μm, but varies with the types of minerals [[10], [11], [12]].When particles are smaller than about 20 μm, value mineral recovery and separation selectivity drop quickly.

This study combines flotation experiments and ab initio simulations to improve the anionic flotation of fluorapatite from Florida waste clay (FWC) by investigating the depressing effects of sodium silicate and citric acid, in presence of sodium oleate (NaOl), on dolomite, quartz, and fluorapatite.

Flotation results showed that fine particles separation (<100 μm) from soil is feasible: separation rates between 15% and 40% are reached with low concentration of surfactant. Granulometric studies showed peak densities around 3, 10 and 40 μm, attributed to phyllosilicates, phyllosilicate aggregates and quartz particles.
