摘要/Abstract

摘要： 为了了解D296树脂从低品位氧化钼矿石的硫酸浸出液中吸附钼的效果，开展了用D296树脂从铁、铝浓度较高的低品位氧化钼矿石的硫酸浸出液中吸附钼的研究，考察了氢离子浓度、吸附时间及吸附温度对D296树脂选择性吸附钼效果的影响；用浓度为10%的氨水和浓度为10%的氯化铵混合溶液为解吸剂，从D296树脂上解吸钼，考察了解吸剂体积、解吸时间对解吸效果的影响。结果表明：在浸出液中氢离子浓度为2 mol/L、吸附温度为50 ℃、吸附时间3 h的条件下，D296树脂对钼的选择性吸附效果最佳；用30 mL解吸剂解吸10 min，钼的解吸效果最佳；利用盐酸酸沉解吸液，使得解吸液中的铁、铝进入母液，钼以结晶沉淀形式析出而高度富集，进而分离与提纯解吸液中的钼。

Abstract: In order to understand the effect of D296 resin on the adsorption of molybdenum from the sulfuric acid leach solution of low-grade molybdenum oxide ore,the research of using D296 resin to adsorb molybdenum from the sulfuric acid leach solution of low-grade molybdenum oxide ore with high iron and aluminum concentrations was conducted,and the effect of hydrogen ion concentration,adsorption time and temperature on the selective adsorption of molybdenum by D296 resin;using a mixed solution of 10% ammonia water and 10% ammonium chloride as a desorbent,desorb molybdenum from D296 resin,investigate and understand the adsorption effect of agent volume and desorption time on desorption effect.The results show that the D296 resin has the best selective adsorption effect on molybdenum under the conditions of hydrogen ion concentration of 2 mol/L,adsorption temperature of 50 ℃ and adsorption time of 3 h;desorption with 30 mL desorbent for 10 min The desorption effect of molybdenum is the best.The desorption solution of hydrochloric acid is used to make the iron and aluminum in the desorption solution enter the mother liquor.The molybdenum is precipitated in the form of crystal precipitation and is highly enriched,and the molybdenum in the desorption solution is separated and purified.
