Abstract: Using spiral launder——weak magnetic separation——strong magnetic separation and flotation craft.Experiment research of removing the iron and removing the sulphur to the gangue of gold mine.Separate through a section gravity,a section of weak magnetic separation,two sections of strong magnetic separation and flotation three times.Get about 40% of the producing rate,iron content is smaller than 0.4%,sulphur content is smaller than 0.03% of the feldspar powder.Can meet the ceramic raw materials request.
