| Abstract: | In this paper, the effect and the quantity of PbO used were discussed.For removing the impurity such as copper, nickel and bismuth in samples, the function relationship between the quantity of impurity and that of PbO needed was established.The particular method to remove rich bismuth was given. The selection principle and method for silicic acidity in melten slay and the quantity of lead button were explained. |
