我国已探明的可溶性钾盐资源有什么特点：
Soluble potash resources in China have been proven what characteristics:
1)储量少。至1996年底，全国保有储量仅4.57亿t KCl。 2)以液体资源为主。国外钾资源储量的主要部分是古代固体层状矿床，占总储量的绝大部分，而我国的钾盐资源储量，主要是液体卤水矿床。
1) less reserves. By the end of 1996, the national reserves of only 457000000 t KCl. 2) to liquid resources. The main part of the foreign reserves of potassium resource is the ancient solid layered deposits, accounting for the vast majority of total reserves, while China's potash resources reserves, mainly liquid bittern deposit.
3)矿石品位低。已探明的现代盐湖层状固体矿层普遍为贫矿，96%是表外矿，KCL含量仅2%-6%。古钾盐层状矿床KCL含量平均为8.81%。国外固体钾盐层状矿床矿石晶位一般为15%-35%K2O。
3) the low grade ore. Proven modern Saline Lake layered solid ore generally lean ore, 96% is a table outside the mine, the content of KCL is only 2%-6%. The ancient sylvite layered deposits the average content of KCL is 8.81%. Foreign solid potash ore crystal layered deposits in general for 15%-35%K2O.
4）质量差。我国古代钾盐矿石中，固体难溶物和不溶物比较多，选矿和加工难度大。
4) poor quality. China's ancient potash ores, solid insoluble and insoluble matter more, beneficiation and processing difficulty.
5）共生组分多。盐湖卤水和地下卤水中与钾共生有大量的镁、钠、硼、锂、溴、碘、铷、铯等元素，有很高的综合利用价值。
5) co-occurrence components and multiple. Saline Lake brine and underground brine and potassium intergrowth have large amounts of magnesium, sodium, boron, lithium, bromine, iodine, rubidium, cesium and other elements, has high utilization value.
6）埋藏浅。盐湖资源出露地表，固体层状钾盐矿一般埋深为25-700m，易开采。
6) shallow buried depth. Saline Lake resources exposed surface, solid layered potassium salt mine general depth of 25-700m, easy mining.
7）可选性差。云南勐野井钾盐矿含泥砂水不溶物比较多，品位低，难以选矿，成本高；盐湖卤水需经日晒光卤石后才能浮选，增加了盐田投资。
7) poor floatability. Yunnan Meng wild well potash mine in silty sand and water insoluble matter more, low grade and difficult to processing, high cost; Saline Lake brine required by the sun can increase the carnallite flotation, Yantian investment.
