摘要
本文简要介绍了减法原地浸出采铀中的结垢问题—结垢的危害、产生的原因及防止的办法。试验表明，结垢的主要成分是ＣａＣＯ３，其中Ｃａ２＋和ＣＯ３２－主要分别来自地下水、矿层和溶浸剂。在溶浸液流动回路中，加人少量的（ＮａＰＯ３）６等化学试剂可有效地抑制结垢的生成。
he paper briefly introduces the problems of incrustation formation-hazards of incrustation,causes of formation and measures of its inhibition, in uranium mining by in-situ alkali leaching. The experiments showed that the main component of incrustation is CaCO3,in which Ca2+ and COt32- mainly come from underground water and ore formation, and leaching solution respectively. Adding a small amount of (NaPO3)6 to the key points of leaching solution flow circuit can effectively depress the incrustation formation.
