珍珠岩尾砂湿法碱溶试验研究

Experimental study on wet process alkali dissolution of pearlite ore tailings

    摘要
  • 摘要: 在常压条件下对珍珠岩尾砂进行湿法碱溶试验,结果表明在90℃时将珍珠岩尾砂用25%NaOH溶液碱溶1.5h,其化学有效成分溶出率在75%以上.

     

    Abstract: Wet process alkli disslution experiment of pearlite ore tailings was made under ordinary pressure. The result shows that if the alkali dissolution of pearlite ore talilings is made with 25%NaOH solution at 90℃ for 1.5 h,its digestion ratio of chemistry valid composition can reach 75% or above.
