摘要
难溶性钾矿资源在我国拥有相对丰富的储量,可用来制备矿物钾肥。采用不同的方法分解钾矿物,将非水溶性钾转化为水溶性钾,能够达到高效利用难溶性钾矿资源的目的。本文介绍了难溶性钾矿的提钾工艺技术,主要包括烧结法、高温熔融法、水热法、低温分解法等,并对提钾工艺进行了比较详细的描述,简单分析了难溶性钾矿提钾技术的发展方向。
Potassium-bearing mineral resources has relatively abundant reserves, and is used to prepare the mineral potassium in our country. Using different methods decompose potassium minerals, which can transform non-water-soluble potassium into a water- soluble potassium, can achieve efficient use of potassium- bearing mineral resources. The technology of extracting potassium from potassium-bearing mine and includes sintering was described, including high temperature melting method, hydrothermal method, and low temperature decomposition method. A more detailed description of extracting potassium craft was discussed and the development direction of technology of extracting potassium from potassium-bearing mine was simply analyzed.
