Abstract:
     The production method of silico phosphate fertilizer is as follows: the yellow phosphorous slag and the semi-finished product of Ca-Mg-P fertilizer are mixed in accordance with the proportion of 1:0.05-20 and dried under the temp. of 600-800 deg C until the moisture content is less than 1%, then the finished product is obtained through pulverizing. The content of available P2O5 is not less than 2%, the soluble SiO2 is not less than 14%. The method provided by said invention is simple and easy.
