摘要
研究了云南昆阳和贵州开阳两种磷矿的反应活性和抗阻缓性,SPSS数学软件回归分析结果表明:磷矿分解率与混酸中硫酸的质量分数之间有良好的线性关系,昆阳磷矿抗阻缓系数为7.104,开阳磷矿抗阻缓系数为7.001,昆阳磷矿的反应活性较开阳磷矿高。
The reactive activity and the resistance to retardancy of Kunyang and Kaiyang phosphate ores were studied. The result of the linear regression analysis carried by using SPSS mathematical software showed that the decomposition rate of phosphate ore had good linear relationship with the concentration of sulfuric acid in mixed acid. The coefficient of resistance to retardancy of Kunyang phosphate ore was 7. 104, and the coefficient of resistance to retardancy of Kaiyang phosphate ore was 7. 001. The reactive activity of Kunyang phosphate ore was better than Kaiyang phosphate ore＇ s.
