我国杂卤石矿资源丰富 ,由于其难溶性和深埋藏的特点 ,至今尚未开发利用。就杂卤石矿的地质特征而言 ,具有溶浸开采的基本地质条件。溶浸开采杂卤石的技术关键在于其中有效成分的溶出。溶浸开采可能成为深埋藏杂卤石的开发的有效途径。溶浸剂种类、浓度 ,矿层组成、厚度 ,矿石有效孔隙度和粒度 ,溶浸剂流速等是影响溶解开采深埋藏杂卤石的技术因素。开发难溶性杂卤石矿对缓解我国钾肥紧张局面具有重大意义。
China’s rich in polyhalite mine resources, due to its characteristics of poor solubility and deep burial, has yet to develop and use. In terms of the geological characteristics of the polyhalite, it has the basic geological conditions of leaching and mining. The key to leaching diopside extraction technology lies in the dissolution of the active ingredients therein. Leaching mining may be an effective way to develop deep-buried polyhalites. The type, concentration, composition of ore layer, thickness, effective porosity and size of ore, flow rate of infiltrant are the technical factors that affect the deep buried polyhalite in solution mining. The development of insoluble sphalerite mine is of great significance for alleviating the shortage of potash fertilizer in our country.
