摘要
本文从羧酸类捕收剂、磷酸类捕收剂和酯类捕收剂三个方面,分别综述了磷矿捕收剂的研究和应用进展。其中羧酸类捕收剂由于低廉的价格,并采用表面活性剂为增效剂,提高了油酸钠或氧化石蜡皂的低温浮选性能,所以羧酸类捕收剂仍然是未来磷矿的主要捕收剂。磷酸类捕收剂由于其具有较好的低温和硬水浮选性能,低廉的价格,是磷矿的很有希望的捕收剂。酯类捕收剂虽具有很好捕收作用,但由于合成工艺复杂,价格较高,竞争力不高。
The research and application ot carboxyhc acid collector, phosphoric acid collector and ester colletor for phosphorous ore are summarized in this paper. The carboxylic acid collector is the predominant one for its low price and the good performance of flotation in low temperature improved by surfactants as synergist. Phosphoric acid collector is promising one for its low price and good performance of flotation in temperature and in low hardwater. Ester collector is not a competitive one for its higher price and complex synthesis process despite its good collection performance.
