Study on Preparation, Characterization and Performance of a Novel Bio-flotation Collector
摘要
Abstract
A series of bio-flotation collectors(BFC) were prepared through catalytic reaction between waste oils and fats and methanol as well as ethanol by adjusting the reaction time in order to improve the hydrophobicity of coal surface in flotation and turn waste into wealth.The GC-MS and FT-IR,Gas Chromatography were respectively completed in order to analyze the main components of BFC,characterize the organic groups of BFC and measure the component contents of BFC.And then the contrastive flotation experiments between BFC and kerosine were done using coal sample of Tunlan 2#.The results showed that the main molecular structures of BFC contains not only methyl ester and ethyl ester,but also hydroxyl and ester group that can form hydrogen bonding groups as well as fatty acid.From the results of flotation that the ash of clean coal was as low as 9.27％ and the tailing ash was up to 76.37％,it can be drawn a conclusion that BFC had better collecting effect and higher collecting selectivity than kerosine.The collector consumption of BFC was low 0.75 kg/t,less 31.8 ％ than that of kerosine under the condition of similar flotation effect.关键词
