摘　　要：水杨醛肟能捕收黑钨矿和锡石,但未见在生产实践中应用。苯甲羟肟酸是水杨醛肟的同分异构体,有相似的官能团。根据浮选药剂的同分异构原理推测,苯甲羟肟酸亦应能捕收黑钨矿和锡石。通过实践证明苯甲羟肟酸不但能捕收黑钨矿和锡石,而且它的合成工艺简单,浮选效果好,在选矿工业生产中得到了推广应用。该实例证明浮选药剂的同分异构原理是正确的。Salicylaldoxime can collect wolframite and cassiterite.But it can not be used in flotation industry.Benzohydroxamic acid is the isomeride of salicylaldoxine.They have similar functional groups.According to flotation reagent isomerism principle,benzohydroxamic acid also collects cassiterite and wolframite.The practice has proof that benzoylhydroxamic acid not only collects cassiterite and wolframite,but also its synthesizing technology is simpler,it has better floatability for cassiterite and wolframite than salicylaldoxime.Its popularization proves that the flotation reagent isomerism principle is correct.
