中国硫酸盐型盐湖资源及无氯钾肥开发展望

Sulfate-type saline resource and development prospect of chloride-free potash fertilizer in China

中国是使用钾肥的大国,但一直以来钾肥靠进口。中国有丰富的盐湖资源,不同类型的盐湖有着不同的开发利用方式。硫酸盐型的盐湖是开发以硫酸钾为主流产品的资源库,针对此,概述了中国硫酸盐型盐湖资源的分布情况和无氯钾肥开发技术现状,认为西部地区尤其是青海和新疆地区盐湖富含硫酸盐型钾资源,但是目前开发利用刚刚起步,是继察尔汗钾肥基地后有望成为又一钾肥生产地区,这将会在某种程度上缓解中国钾肥缺口状况,最后提出了几点利用硫酸盐型盐湖资源生产以硫酸钾为主的无氯钾肥的建议。

China is a big country of using potash fertilizer, but for a long time it primarily depends on import. China has abundant saline resources ,and different types of the salt lake have different modes of development and utilization. The sulfate -type salt lake is the resource reservoir for developing potassium sulfate product and so on. Aiming at this ,the distribution of sulfate - type saline resources and current status of development technology of chloride - free potash fertilizer in China were reviewed. It is believed that the west of China ,especially Qinghai and Xinjiang have sufficient sulfate - type potassium resources. However , the development and utilization of saline resources in these regions are just at their very outset. But these regions still promise well as the second potash fertilizer producing areas after Chaerhan potash fertilizer base, which will relieves the shortage of potash fertilizer of China to a certain extent. At last, several suggestions on development of potassium sulfate -dominant chloride -free potash fertilizers by using
