摘要
Agricultural potassium sulphate is one of the most important non-chloride potash, which is the main fertilizer of avoid chlorine crop. Soluble potassium resource is bare in China, while insoluble potassium resource with the main mineral of microcline is extremely abundant. The microcline powder used is collected from Mountain Changling, Luonan county of Shaanxi Province. The chemical analysis results showed that the main chemical components of the powder are SiO2, Al2O3 and K2O, the K2O content is up to 13.56% (shown in table 1).
