Experimental Study on Reducing Tungsten Loss Rate of Scheelite Leaching Residue AITranslate
Abstract AITranslate
A scheelite ore in Henan was processed by soda pressure boiling leaching.In order to reduce the tungsten content in the leaching residue from original 4%to less than 0.5%,the effects of roasting time,sodium carbonate concentration,pressure leaching time and stirring speed on the loss rate of tungsten in the scheelite leaching residue were investigated.The results show that under the conditions of 40 min roasting time,160 g/L sodium carbonate concentration,120 min pressure leaching time,300 r/min stirring speed,205℃pressure leaching temperature and 5∶1 liquid-solid ratio,the tungsten content in the leaching residue is less than 0.15%,which basically minimizes the loss rate of tungsten in the leaching residue and can provide a valuable reference for the production of enterprises.
