Abstract: Hydroxamic acid compounds，which contain the functional groups of hydroxyl oximido with high coordination activity，can chelate with metal ions to form a stable ring and have extensive applied values. It is a very reactive chelating agent. The structure characteristics and chemical properties of hydroxamic acid compounds were introduced. The synthesis methods of hydroxamic acid and hydroxamic acid polymer were reviewed，with emphasis on hydroxylamine method. The updated progresses of their application were also reviewed in the fields of medicine，flotation and metallurgy and the function mechanism of hydroxamic acid on mineral surface to flotation is recommended In order to broaden the scope of its application in less new product，high production costs and low toxicity in the process of preparation should be paid more attention. New product，high efficiency，green industry should be the direction of preparation of hydroxamic acid.
