金矿尾矿的除铁硫研究

STUDY ON THE GANGUE OF GOLD MINE REMOVE IRON AND REMOVE SULFUR

用螺旋溜槽 -弱磁选 -强磁选 -浮选工艺 ,对金矿尾矿进行除铁除硫试验研究 ,经过一段重选、一段弱磁选、两段强磁选和三次浮选 ,可得到产率约 4 0 %、含铁小于 0 4 0 %、含硫小于 0 0 3%的长石粉 ,可满足陶瓷原料要求。

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.
