Extractant is a chemical reagent that forms a raffinate soluble in organic phase with the extracted substance. In hydrometallurgy, the function of the extractant is to extract the extract into the organic phase through a chemical reaction with the extracted metal, and to extract the extracted metal from the organic phase to the aqueous phase through some chemical reaction, so as to achieve the purpose of metal purification and enrichment. Extractant is the most important factor affecting the success or failure of extraction process.At present, P507 (2-ethylhexyl mono-2-ethylhexyl phosphate), P204 (diisooctyl phosphate) and TBP (tributyl phosphate) produced by the company are phosphorous extractant, mainly used for extraction and separation of rare earth, nickel, cobalt, lithium and other non-ferrous metals.
2-ethylhexyl phosphate mono-2-ethylhexyl ester:Commonly
 known as P507Extractant, which is divided in rare earth metals Separation,transformation, nickel and cobalt separation, and Recycling and utilization of ternary energy storage materials Has a wide range of applications.
