2023.12.1 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 at

2020.7.20 The anionic reagents have been used in the flotation separation of fluorite from barite, such as sodium oleate (NaOl) and sodium petroleum sulfonate (SPS) [8,9]. These anionic collectors are non-selectivity for the fluorite and barite [10], thereby they need to be used with the depressant to inhibit the flotation of barite.
