摘　　要：钼酸铵生产过程中产生的酸性废液，经中和、过滤、滤渣热碱浸取、滤液蒸发浓缩等步骤，可回收废液中约７９％ 的钼，并获得ＮＨ４ＮＯ３、ＮＨ４ Ｃｌ混合液体肥料。Waste acid liquor from ammonium molybdate production is neutralized and filtered,then the filter cake is extracted by hot alkaline and the filtrate is enriched by evaporation.The process can recover molybdenum in the waste liquor with 79% recovery rate and produce a mixed liquid fertilizer containing NH 4NO 3 and NH 4Cl.
