可溶性矿床的综合开采及利用

Integrated mining and utiliation of soluble trona deposit

锡林郭勒苏尼特碱业有限公司的天然碱矿床是可溶性矿床 ,过去采用单一的采掘机械开采 ,回采率仅为78%左右。为此 ,公司组织技术人员总结经验、分析造成损失的原因 ,在扩采的基础上采用了多种采掘机械联合开采和配套碱田工艺系统进行碱份回收的综合工艺 ,大幅度减少了损失和贫化 ,回采率提高到 95 %以上 ,使有限的碱资源得以充分利用。

A recovery of 78% was only obtained by mining soluble deposit with single machinery process in Xilingele Trona Mine.For incrcase of the recovery and making use of trona resources,comprehensive process,multi machinery mining combined with trona field recovery process system,are used,in results,increasing recovery to more than 95% reducing the loss and dilution rate.
