摘　　要：对近10年来电位滴定法在矿石分析过程中样品前处理及检测方法进行了综述。矿石样品处理方法主要包括干法熔融、湿法消解、微波消解等,其中湿法消解和干法熔融是矿石样品常用的前处理方法,但是新出现的微波消解法已被接受与广泛推广。铁矿石、铬矿石、锰矿石、铜精矿等不同矿石中主成分的分析工作在电位滴定法得到一定程度的应用,其中自动化程度高的微波消解-自动电位滴定法是电位滴定法未来发展的趋势。This paper focused on the research progress of digestion preparation and determination methods in ores in recently ten years.The ores sample preparation contained dry digestion,wet digestion,microwave digestion and so on.Wet digestion and dry digestion were widely used in the determination.But the new microwave digestion has been widely accepted and promoted.Potentiometric titration analytical method has been applied in iron ore,chromium ore,manganese ore and copper concentrate.Microwave digestion-potentiometric titration is the trend of future development because of high degree of automation analysis.
