; Abstract: The separation techniques of vanadium and molybdenum were summarized, and a new method of removal V(Ⅴ) from Mo(Ⅵ) by adsorption with chelate resin was presented. Nine kinds of chelate resins were used to investigate the adsorbent capability of V(Ⅴ) in ammonium molybdate solution with static method. The test results show that DDAS, CUW and CW-2 resins can easily......
involves electric charge interaction, hydrogen bonding interaction and complexation, with the proposed formation of an O, O-five membered rings chelate compound. Key words: fine cassiterite; flotation; alkyl hydroxamic acid; chelate 1 Introduction As the most commonly used metal all over the world, tin is usually found as oxide minerals in nature and is extracted from tin-containing ores [1,2......
J. Cent. South Univ. (2016) 23: 1058-1065 DOI: 10.1007/s11771-016-0355-x Flotation of a new chelate collector on fine refractory iron ore-containing carbonate WANG Ting-xia(王婷霞)1, ZHU Yi-min(朱一民)2... chelate collector W-2 was synthesized. At 30 °C, condition flotation tests on mixed magnetic concentrate of Donganshan sintering plant established the best reagent system. With the optimum reagent system......
Fe–EBT Chelate Complex: A Novel Mean for Growth of α-FeOOH and γ-Fe2O3 NanostructuresGajanan Pandey摘 要:Acicular goethite(a-Fe OOH) and worm-like maghamite(γ-Fe2O3) nanostructures have been prepared adopting a novel route, using Na2[Fe(HL)2(H2O)2] chelate complex in alkaline medium. It is found that concentration of hydrated Fe(III) ions increased......
