TRIAL CONCENTRATION OF DONG'ANSHAN MINE'S IRON ORE WITH ALKYLHYDROXYOXIME ACID

To find a more effective collecting agent replacing talloil oxidized paraffin soap for concentratingDong' anshan Mine's iron ore, this paper discusses the appliction of C5～C9 alkylhydroxyoxime acid in iron oreflotation and introduces the small-scale comparision test. The test results show that under suitable conditions, itcan be used for field production.
