Stibnite froth flotation: A critical review - ScienceDirect
15/03/2021· Zhou et al. (2020) report that for every ton of stibnite ore processed in the flotation circuit at the Xikuangshan Antimony Mine in Hunan, China, 3.5 m 3 of water are consumed, while producing 920 kg of tailings and 0.2 kg of dust. Their comprehensive environmental study quantified the contribution of the tailings from the concentrator to the release of potentially toxic elements associated with mineHow Antimony is Processed by Flotation - 911 Metallurgist,01/04/2018· Flotation is an efficient method to separate stibnite from other gangue minerals. Stibnite can be efficiently floated by xanthates in an acidic medium below pH 5 (Huang, 1987). At a pH above 5, stibnite does not respond well to xanthates. Due to the presence of alkaline gangues in most deposits, it is not economical to float stibnite in an acidic slurry. Instead, the flotation of stibnite is conducted atFlotation studies of low grade stibnite ore from Krinj,,Made available by U.S. Department of Energy Office of Scientific and Technical Information,RECOVERING MERCURY FROM CINNABAR-STIBNITE ORE BY,nabar-stibnite ore by bulk flotation and controlled-atmosphere roasting of the concentrate.

But the clay minerals (kaolinite and illite), pyrite and arsenopyrite in the ore will bring some difficulties to flotation. Through on the research of the slurry regulator, stibnite collector and gangue mineral inhibitor, better flotation index was obtained. Under the condition of the Sb raw ore grade 2.25%, the flotation index of the concentrate contains Sb
