在分析某硅板岩矿石特性及酸浸行为的基础上,研究了该硅板岩矿石铀难浸的主要原因在于粘土矿物对铀的牢固吸附。采用氧化焙烧的方法,可使硅板岩矿石中的粘土矿物结构遭到破坏,铀变得易于浸出。 某硅板岩铀矿石属难浸矿石。本文试图从矿石矿物学分析入手,研究铀难浸的原因。 Based on the analysis of the characteristics of a certain slate ore and its acid leaching behavior, the main reason for the difficult impregnation of uranium in this slate ore is the firm adsorption of uranium by clay minerals. The use of oxidative roasting can destroy the structure of clay minerals in the slate ores and allow uranium to leach easily. A silicon slate uranium ore is difficult to leach ore. This paper attempts to start from the mineralogy analysis of ore, uranium difficult to study the cause of the dip.
