羟肟酸类捕收剂应用现状及展望
Application status and prospect of hydroxamic acid collector
摘要
Abstract
Hydroxamic acid collectors are a class of chelating collectors with good selectivity,commonly used for flo-tation of oxidized ores such as copper oxide,ilmenite,cassiterite,rare earth ores,tungsten ores,etc.This article introduces the structure and chelation properties of hydroxamic acid,summarizes the mechanism of action and synthe-sis methods of hydroxamic acid,and reviews the application status of alkyl hydroxamic acid,benzyl hydroxamic acid,salicylic hydroxamic acid,2-hydroxy-3-naphthyl hydroxamic acid,hydroxamic acid combined with other drugs,and new hydroxamic acids.It also looks forward to the important research directions of hydroxamic acid collectors in the future from the aspects of hydroxamic acid structure,reducing synthesis costs,improving synthesis efficiency,com-bined drugs,and activation with metal ions.关键词
