Synthesis and utilization of a novel oleate hydroxamic acid …
In the pH range of 8–10, the barite species are Ba 2+ and SO 4 2-, and after pH 11, the amount of BaOH + in solution rises (Xu et al., 2022). More HPO 4 2-was consumed by BaOH +, resulting in the amount reacted with Ba 2+ decreased. Therefore, SHMP loses its depressed ability on barite, leading to the flotation recovery increased …
Froth flotation of fluorite: A review
Therefore, fluorite and barite exhibit similar floatabilities, and their separation by flotation is difficult [169, 170]. Multiple flotation stages are usually required. The first step is to enrich fluorite and barite through mixed flotation in which sodium oleate and sodium silicate are selected as the collector and depressant, respectively [171].
