The impact of sulphur overcharge percentage,heating temperature and heating time on percent formation of PbS are studied,and the PbS overcharge percentage,heating time and agitation time for decoppering from lead bullion are investigated too.

• 在本实验中；对硫加入过量率、加热温度、加热时间等制备PbS的工艺条件进行了研究；并确定了加PbS除铜工艺的最佳硫化铅用量；最佳搅拌时间等技术条件.
