Investigation on flotation separation of chalcopyrite from

Jun 15, 2019  The efficient separation of chalcopyrite from arsenic-bearing minerals, especially arsenopyrite, remains a challenge in pract. In this , a novel reagent of N-Butoxycarbonyl-O-Isobutyl Thiocarbamate (NBOIT) was employed in both single and mixed binary mineral flotation, and it proved to be highly effective for the flotation separation.

Investigations on flotation separation of scheelite from

It has been found out that the preferential flotation separation of scheelite from calcite could be realized by using phosphates as flotation depressants, by control of pulp pH range of 9.0 for Na 3 PO 4, 8.0 for Na 4 P 2 O 7 and 9.510.5 for (NaPO 3) 6, respectively (Changgen and Yongxin, 1983, Gao et al., 2018). However, the best pH ranges

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Selective Flotation Separation of Feldspar in Non Fluoride

Since the inception of the feldspar flotation process using hydrofluoric acid by O’Meara the process has achieved a great commercial success. In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector.
