察尔汗盐湖钾矿资源利用探讨

Discuss on the Utilization of Potassium Resources in Qarhan Salt Lake

察尔汗盐湖是一个以钾为主、固液并存的大型钾镁盐矿床,矿区从西至东,分为别勒滩采区(西采区)、达布逊采区(中采区)、及察尔汗采区(东采区),青海盐湖股份公司是我国最大的钾肥生产基地,年生产氯化钾^([1-2])500万t,是我国钾肥行业的“压舱石”,基于盐湖钾盐资源储量情况和我国钾肥行业总体供需形势,文章主要探讨了察尔汗盐湖钾矿资源的储量,以及利用过程中存在的问题:固液转化率、盐田生产率、尾液利用率,资源开采与水资源不足的问题、资源开采与环境保护存在的矛盾的问题,针对以上问题提出了相应的合理措施及建议。

Chaerhan Salt Lake is a large potassium magnesium salt deposit dominated by potassium and coexisting with solid and liquid.From west to East,the mining area is divided into Bieletan mining area(West mining area),Dabuxun mining area(middle mining area)and Chaerhan mining area(East mining area).Qinghai Salt Lake Industry Co.,Ltd.is the largest potash fertilizer production base in China,with an annual production of 5million tons of potassium chloride.It is the“ballast stone”of China’s potash fertilizer industry,Based on the reserves of potash resources in the salt lake and the overall supply and demand situation of China's potash fertilizer industry,this article mainly discusses the reserves of potassium resources in the Qarhan Salt Lake,as well as the problems existing in the utilization process:solid-liquid conversion rate,salt field productivity,tail liquid utilization rate,the problems of insufficient resources exploitation and water resources,and the contradictions between resources exploitation and environmental protection,and puts forward corresponding reasonable measures and suggestions for the above problems.
