【摘要】 本文研究了淅川钒矿钠化焙烧物料水浸液弱酸性铵盐沉钒的工艺条件，结果表明，多钒酸铵沉钒的最佳工艺条件为：沉钒ｐＨ值为６．０，ＮＨ＿４Ｃｌ加入量３０ｇ／Ｌ，搅拌时间９小时。在该工艺条件下，若浸出液中Ｖ＿２Ｏ＿５含量大于６．５ｇ／Ｌ，多钒酸铵沉钒率≥９７％。更多还原

【Abstract】 The precipitation conditions of vanadium with NH₄ Cl from the leaching solution ofthe roasted vanadium ore with NaCl were studied. The optimal conditions are pH 6.0, the quantityof NH₄Cl,30 g/L,and the churning time, 9 hours especially.In these conditions,the precipitatingrate of ammonium polyvanadate is over 97%。更多还原
