“…The results are shown in Figure 3. In the flotation process, increasing the amount of collector is beneficial to improve the recovery of concentrate, but the excessive amount of collector will result in the flotation of other nonpurpose minerals, thereby affecting the grade of concentrate [17][18][19].With the increase of butyl xanthate dosage, the grade of cobalt-sulfur concentrate decreases regularly, and the recovery of cobalt increases accordingly. When the dosage of butyl xanthate increased to 30 g/t, the cobalt grade was 1.22%, and the cobalt recovery rate was 75.78%.…”

There is 0.032% cobalt and 0.56% sulfur in the cobalt-bearing V–Ti tailings in the Panxi Region, with the metal sulfide minerals mainly including FeS2, Fe1−xS, Co3S4, and (Fe,Co)S2, and the gangue minerals mainly including aluminosilicate minerals. The flotation process was used to recover cobalt and sulfur in the cobalt-bearing V–Ti tailings. The results showed that an optimized cobalt–sulfur concentrate with a cobalt grade of 2.08%, sulfur content of 36.12%, sulfur recovery of 85.79%, and cobalt recovery and 84.77% were obtained by flotation process of one roughing, three sweeping, and three cleaning under roughing conditions, which employed pulp pH of 8, grinding fineness of < 0.074 mm occupying 80%, flotation concentration of 30%, and dosages of butyl xanthate, copper sulfate, and pine oil of 100 g/t, 30 g/t, and 20 g/t, respectively. Optimized one sweeping, two sweeping, and three sweeping conditions used a pulp pH of 9, and dosages of butyl xanthate, copper sulfate, and pine oil of 50 g/t, 15 g/t, 10 g/t; 25 g/t, 7.5 g/t, 5 g/t; 20 g/t, 5 g/t, 5 g/t, respectively. Optimized one cleaning, two cleaning, and three cleaning condition dosages of sodium silicate of 200 g/t, 100 g/t, 50 g/t, respectively. Study of analysis and characterization of cobalt–sulfur concentrate by X-ray diffraction (XRD), automatic mineral analyzer (MLA), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) showed that the main minerals in cobalt–sulfur concentrate are FeS2, Co3S4 and (Fe,Co)S2, of which FeS2 and (Fe,Co)S2 accounted for 65.64% and Co3S4 for 22.64%. Gangue minerals accounted for 11.72%. The element Co in (Fe,Co)S2 is closely related to pyrite in the form of isomorphism, and the flotability difference between cobalt and pyrite is very small, which makes it difficult to separate cobalt and sulfur. Cobalt–sulfur concentrate can be used as raw material for further separation of cobalt and sulfur in smelting by pyrometallurgical or hydrometallurgical methods.

“…Previous research showed that pyrite has some natural floatability and a small amount may be floated without collector (Han et al, 2018;Corin et al, 2018). In the presence of xanthate, 70 to 80% recovery of pyrite can be achieved by flotation in acidic to neutral pH conditions due to the formation of dixanthogen, while at other pH values, the recovery is much lower (He et al, 2011;Kelebek et al, 2007;Owusu et al, 2013).…”

In this paper, to produce a saleable magnetite concentrate with a sulfur level below 0.20% and recover sulfur concentrate, flotation and magnetic separation tests were undertaken. Results showed that the optimum conditions of flotation were established as follows: grinding fineness of 90% particles passing 0.074mm, pH 6, 400 g/t of CuSO4, and 400 g/t of combined collectors. Under these conditions and magnetic separation, S grade of the magnetite concentrate was reduced from 3.20% to 0.18%, and the Fe grade improved from 57.29% to 71.17%. At the same time a sulfur concentrate with S grade of 38.05% and recovery of 91.32% was also obtained. The XPS results showed that the addition of CuSO4 benefited the formation of hydrophobic Sn2-/S0 and Cu+-xanthate, enhancing pyrrhotite floatability. The flotation separation efficiency could be enhanced using a mixture of collectors, and collector mixture demonstrated three synergetic effects, namely enhanced S recovery, improved adsorption behavior of the collectors and enhanced hydrophobicity of pyrrhotite surface.

“…It is well known that using the cast iron media in grinding has a detrimental effect on the flotation of sulfide minerals (Adam et al, 1984;Peng et al, 2003aPeng et al, , 2003bDeng et al, 2013;Long et al, 2020). Also, it is believed that using inert grinding media, such as ceramic and zirconia media, can improve the flotation recovery of sulfide minerals compared with cast iron media which results in the generation of iron oxyhydroxide species coating on the mineral surfaces (Huang and Grano, 2006;Bruckard, 2011;Corin et al, 2018;. However, most researches have been mainly focused on the deteriorating effect of cast iron media on the sulfide minerals.…”

Grinding, an essential procedure before flotation, to some extent, determines the flotation behavior of minerals. In this study, the effect of grinding media on the flotation behavior of fluorite using sodium oleate (NaOl) as a collector was investigated via micro-flotation experiments, zeta potential measurements, scanning electron microscopy-energy dispersive spectrometry (SEM-EDS) and X-ray photoelectron spectroscopy (XPS) analyses. The results indicated that, compared with the fluorite particles ground by ceramic media, the ones ground by cast iron media adsorbed less NaOl, resulting in lower flotation recovery. The lower flotation recovery of fluorite particles ground by cast iron media resulted from the coating of the hydrophilic Fe precipitates generated in the grinding, including Fe(0), Fe(OH)2, and Fe(OH)3 on their surfaces. These Fe precipitates may cover the Ca active sites and increase the hydration membrane which can inhibit the further NaOl adsorption. This research reveals the effect of grinding media on the flotation behavior of fluorite and guides for media selection in disposing of fluorite ore.
