Abstract: Dialkyldi(or mono)thiophosphoric(or phosphinic) acid compounds containing sulfur and phosphorus，or sulfur，phosphorus and oxygen atoms，could easily form chelates with metal ions and have been widely used as metal extractants，corrosion inhibitors，flotation collectors，lubricating oil additives，or agricultural pesticides and herbicides. This paper reviews the interaction of dialkyldi(or mono)thiophosphoric(or phosphinic) acids with metal ions，the applications of dithiophosphate compounds such as dicresyl and dialkyl dithiophosphates in the mineral flotation，and the utilization of di(or mono)thiophosphinic acids in the extraction recovery of zinc，cadmium，copper，iron and precious metals and in the separation of cobalt from nickel，or actinides from lanthanides. Based on the review results，further investigations of dialkyldi(or mono)thiophosphoric(or phosphinic) acids were conducted，which included their new synthetic methods and extraction performances.

Key words: dialkyldi(or mono)thiophosphoric(or phosphinic) acid, flotation, metal extraction
