Abstract:A novel method is developed for designing and/or directional searching the reagents using in separation of resemble elements．According to the differences in chemical and structural characters of WO42- and MoS42- the actions of them to separator molecular such as bonding， hydrophile/hydrophobia and geometry are discussed by using mineral flotation as reference．Metal sulfides are chosen for separation of W and Mo. Besides， the optimization of process and the extending to separation of other elements are discussed．Practice shows that novel theory is effective．
Key words: separation of resemble elements; molecular design; tungsten metallurgy; adsorbing agent
