Abstract:Crude lead in some places contains silver 900-1000 grams and gold,22-27 grams a ton. If we distil this kind of lead three times continuously and once interruptedly in the vacuum furnace,the residual alloy in which 75% of it is silver and 2.4% of it is gold will be pro- duced.
Keywords:vacuum distillation  crude lead  silver  gold  concentration
