| Abstract: | The effects of temperature,time,atmosphere,content of reductive,basicity and additive etc.on the volatility of Sn,Pb,Cu,Zn and As in pellets of tinmiddling have been studied,and the optimum conditions for roasting have been
given.The mechanism of chioridizing volatilization of the metals in pellets has been discussed by thermodynamic calculation of the related chemical reactions. |
