Flotation tests indicate that the effective depression of talc flotation occurred in the pH range of …
In the case of talc flotation, the recovery of talc dropped as the pullulan dosage increased. The adoption of a 300 mg/L dosage of pullulan reduced the talc flotation recovery to ∼ 16 %, and the pullulan dosage for talc depression was much higher than that in previous work (Ning et al., 2021). When calcium ions were added before …
1. Introduction. Talc is a Mg-containing TOT type silicate mineral with the chemical formula of (Mg 3 (Si 2 O 5) 2 (OH) 2)(Zhan et al., 2019; C. Li et al., 2021b; Burkett et al., 2022), the unit layer composition of two layers of silica tetrahedron held together with magnesium‑oxygen octahedron, and magnesium ion is filled in the octahedral void with …
Flotation is widely adopted to separate sulfide minerals from talc (Zhong et al., 2021, Farrokhpay et al., 2018, Witney and Yan, 1997). However, in the flotation beneficiation of sulfide minerals, such as chalcopyrite, talc easily enters into copper concentrate due to its natural floatability, then affecting the copper grade in concentrate.
Moreover, the adsorption mechanism of TA with chalcopyrite and talc was examined after TA was chosen as the separation depressant for chalcopyrite and talc. Single-mineral flotation test results found that at optimal pH and TA and sodium butyl xanthate (SBX) dosages, the flotation recoveries of talc and chalcopyrite were 9% and …
