Abstract�� Using apparatus for determing the solvent extraction equilibrium and selecting the tributylphosphate as solvent,benzene as diluent,the solvent extraction equilibria of W were determined systematically.The effects of different condition on extraction equilibrium were studied.The data were useful for industrial process design and engineerning optimization.

Keywords�� tungsten solvent extraction of metals tributylphosphate
