摘　　要：通过单矿物沉降试验,研究了碳酸钠、氢氧化钠和硅酸钠对微细粒赤铁矿分散行为的影响。试验结果表明:与碳酸钠相比,氢氧化钠和硅酸钠对微细粒赤铁矿有更好的分散效果;氢氧化钠和硅酸钠对微细粒赤铁矿的分散具有协同作用;在一定范围内增强搅拌强度有利于微细粒赤铁矿的分散,但搅拌强度超过某一临界值后分散效果变差。The influence of sodium carbonate, sodium hydroxide and sodium silicate on dispersion of hematite fines were studied. The results showed that hematite was better dispersed by sodium hydroxide and sodium silicate, compared with sodium carbonate; There is a synergistic action between the sodium hydroxide and sodium silicate on the dispersion of ultra - fine hematite. The hematite can be better dispersed with the increase of stirring speed in a range, but the dispersion becomes worse when the stirring speed exceed a critical value.
