摘要
研究了采用硝酸铁从低钨高钼溶液中吸附分离钨钼的工艺条件,考察了Fe3+/W摩尔比、pH值、搅拌速度、反应时间、反应温度、静置时间等对吸附效果的影响.结果表明:在Fe3+/W摩尔比为 6、pH值为 9.0、搅拌速度600 r/min、反应时间 1h、反应温度 40℃、静置时间 15h 的条件下,溶液中的钨钼比由 2.08×10-2 降至6.52×10-4,钼损率仅为3.56%,钨钼分离效果显著,且硝酸铁中的Fe3+循环利用效果较好.
Abstract
The technology of adsorption separation of tungsten and molybdenum from low-tungsten and high-molyb-denum solution by ferric nitrate was studied.The effects of the mole ratio of Fe3+/W,pH value,stirring speed,re-action time,reaction temperature and standing time on adsorption were investigated.The results show that:Under the conditions of the mole ratio of Fe3+/W multiple of 6 times,pH 9.0,stirring speed of 600 r/min,reaction time of 1 h,reaction temperature of 40℃ and standing time of 15 h,the tungsten-molybdenum ratio of solution can be reduced from 2.08×10-2 to 6.52×10-4,and the molybdenum loss rate is only 3.56% .The separation effect of tungsten-molybdenum is remarkable.The Fe3+ in ferric nitrate has a good recycling effect.
