液相开采化学矿,是将液体注入矿层进行溶解,再将溶液回收至地面。适于这类开采的化学矿产主要有自然硫、天然碱、钾盐及芒硝等,其赋存特点是一般埋藏较深,杂质含量较高,或者产状不规则,多呈层状、薄层产出等。除可溶性钾盐外,我国这方面矿产资源较为丰富,先后在河南、山东、内蒙、青海、四川等省都有发现,储量还相当大。有关液采技术,在波兰、美国和伊拉克等国 Liquid mining chemical ore, is the liquid injected into the mine to dissolve, and then recovered to the ground solution. Suitable for this type of mining chemical minerals are mainly natural sulfur, trona, potassium salt and Glauber’s salt, which are characterized by the general buried deep, high impurity content, or irregular-shaped, mostly layered, thin layer Output and so on. In addition to soluble potassium salt, our country is rich in mineral resources in this area. It has been discovered in Henan, Shandong, Inner Mongolia, Qinghai, Sichuan and other provinces and the reserves are still quite large. Liquid extraction technology in Poland, the United States and Iraq and other countries
