异羟肟酸是一种较老的有机化合物,早为人们所知。但作为浮选捕收剂的研究还是近二十年来的事情。本世纪六十年代初,苏联开始研究用脂肪族异羟肟酸浮选黑钨矿、钨锰矿(C.A.55:14266a),后来又采用IM—50(即—50,脂肪族异羟肟酸钠)浮选烧绿石(C.A.55:17456b),烧绿石—锆石(C.A.63:2655a),并获得良好结果。在这之后,美国也进行了用辛基异羟肟酸钾浮选硅孔雀石的研究,取得显著效果(C.A.64:9298a)。民 Hydroxamic acid is an older organic compound and has long been known. However, the study of flotation collector is still the last two decades. In the early 1960s, the Soviet Union began to study the use of aliphatic hydroxamic acid flotation wolframite, wolframite (CA55: 14266a), and later with IM-50 (ie, -50, aliphatic sodium hydroxamate ) Flotation pyrochlore (CA55: 17456b), pyrochlore-zircon (CA63: 2655a) with good results. Since then, the United States also conducted a study of the flotation of silicon malachite with potassium octyl hydroxamate, with remarkable results (C.A. 64: 9298a). people
