摘　　要：随着化工行业的发展,含钨废料也越来越多。为了充分回收利用钨和建设绿色化工,本文研究并完成了从含钨废料中回收制备三氧化钨的工艺流程设计及其基本工艺参数的确定。实验证明,从含钨废料中回收制备三氧化钨是可行的。通过大量的探索,原料经煅烧、用氨水浸取,通过蒸发结晶制仲钨酸铵。当仲钨酸铵结晶温度为70℃时,目前钨的最高回收率为75.6%。With the development of chemical industry, there are more and more waste materials which contain tungsten. In order to recovery tungsten and building Green Chemical Industry, it was investigated and finished a technological process designing to reuse and reabricate tungsten trioxide, followed the confirmation of some basic process parameters in the experiment. The experimental data show that the recovery process is feasible. After enormous experiment, material were calcined, then soaked and extracted by ammonia, and evaporated and crystallized into APT. the maximum recovery rate reached 75.6% when APT crystallization temperature is 70℃.
