摘　　要：用合成的物系研究了氧化铝对钼浸出的影响。MoO3-Al2O3系中未形成新的含钼化合物,影响钼浸出的因素主要是晶格互溶和吸附作用。Al2O3对Na2MoO4溶液中Mo的吸附符合弗伦德利希(Freundlich)理论。NaOH对Al2O3的溶解影响钼的浸出。pH值在9附近,Al/Mo比增长很快。The effect of alumina on the leaching of molybdenum is investigated by synthesized homologues.Mutual compound is unformed in the MoO3-Al2O3 homologue,and the main factors affecting the leaching of molybdenum are crystal lattice mutually dissolution and adsorption effect.The adsorption of alumina to molybdenum in Na2MoO4 solution obeys Freundlich adsorption theory.The dissolution of alumina in NaOH solution influences the leaching of molybdenum.When the pH value is near 9,Al/Mo ratio increases quickly.
