摘要
主要研究六偏磷酸钠和腐植酸纳２种分散剂分别对细粒高硫煤、煤系黄铁矿悬浮液的分散作用，考察了分散剂用量、介质ｐＨ值对细粒煤与煤系黄铁矿选择性分散的影响。
The dispersion status of fine high sulfur coals and coal-derived pyrite in suspen-sions by sodium hexametaphosphate or sodium humate dispersant were studied respectively in thispaper.The effects of dispersant dosage,suspension liquid pH on selective dispersion of fine highsulfur coals and coal-derived pyrite were mainly investigated.
