中文摘要：

采用沉降抽液法研究了碳酸钠、氢氧化钠和硅酸钠对微细粒胶磷矿分散行为的影响。研究结果表明：相对于碳酸钠，氢氧化钠和硅酸钠对提高微细粒胶磷矿分散效果的作用不明显；在较高的pH条件下，胶磷矿的分散效果较好；在一定程度上提高搅拌速度有利于胶磷矿的分散，但过分提高则无益。

英文摘要：

The effects of sodium carbonate, sodium hydroxide, and sodium silicate on the dispersion behavior of ultrafine eollophanite were investigated by adopting the sedimentation and liquid removal method. The results showed that comparing with sodium carbonate, sodium silicate and sodium hydroxide had no obvious effects on dispersion of ultrafinc collophanite ; The dispersion of collophanite was effective at a higher pH value ; And the collophanite was better dispersed by improving the stirring speed to be a certain extent, but more stirring had no benefit on the dispersion.
