富钾岩石制取矿物钾肥生产现状与前景展望

我国富钾岩石分布广泛，资源十分丰富。利用富钾岩石制取矿物钾肥潜力巨大，积极开展富钾岩石资源的综合利用、补充我国钾肥来源具有重要意义。目前国内已成功开发出以石灰为激发剂、在半湿状态下用富钾岩石生产钾硅钙微孔矿物肥料的静态水热法新工艺。介绍国内富钾岩石资源状况，利用富钾岩石制取矿物钾肥的生产工艺、技术进展及前景展望，并提出...

Production status and prospect of mineral potassium fertilizer from potassium-rich rock

The potassium-rich rock is widely distributed with the very abundant resources. The mineral potassium fertilizer production from potassium-rich rock is potential and important for adding potash fertilizer source. The static hydrothermal production process of mineral potassium fertilizer from potassium-rich rock with lime as the inspire agent has been developed in China. The situation of potassium-rich rock resources, as well as the production process, progress and prospect of mineral potassium fertilizer from potassium-rich rock are introduced, some suggestions for development are proposed.
