parameters, including pH, ammonium dibutyl dithiophosphate concentration, stirring strength and kerosene addition. It is found that the maximal floatability of jamesonite fines is induced by ammonium dibutyl... that the floc flotation is closely correlated with the size of flocs, which is strongly influenced by the stirring strength and enhanced by the addition of a small amount of kerosene. The results of FTIR......
: Crude selenium was prepared from selenium acid mud using a new technology of kerosene desulphurization, oxidization-leaching and reduction-extraction of selenium. The results show that kerosene can... is more than 92%, respectively. Key words: kerosene desulphurization; selenium acid mud; H2NCSNH2 硒属于稀散元素,在自然界中有工业开采价值的单独成矿很少.硒有着广泛的应用领域,但一直是严重短缺的金属资源[1-3].目前,提取硒[4-7]的主要原料有电解精炼铜的阳极泥,铅鼓风炉的烟尘,硫铁矿制酸厂的......
analysis on wrist pin bore of aero-piston kerosene engine PAN Zhongjian1, 2, HE Qinghua1, 3, DENG Yu1, 2 (1. School of Mechanical and Engineering, Central South University, Changsha 410083, China; 2...: By establishing mechanics-mathematical model of wrist pin bore installed in aero-piston kerosene engines, the force created by thread connection position between piston crown and piston skirt was analyzed......
pH, collector concentration and kerosene addition. The results show that the floc flotation closely correlated with the size of flocs and the particle hydrophobicity, but was not lowered...%, in comparison with conventional flotation obtaining floatability of about 60%. It also has been found that a small addition of kerosene greatly improved the floc flotation because of the formation......
,Siksha’O’Anusandhan University, Bhubaneswar-751030, Odisha, India)Abstract:The extraction and separation of Cu(II) and Fe(III) from HCl media using Cyanex 921 in kerosene were investigated...) was studied using 0.1 mol/L Cyanex 921 in kerosene. Maximum separation was achieved from 2 mol/L HCl containing 0.001 mol/L Cu(II) and 0.005 mol/L Fe(III) with 0.1 mol/L Cyanex 921 in kerosene. Feasible......
