The extraction of scandium from one certain deposit was studied by the liquid membrane emulsion technique using P507-Span80-sulphonating kerosene-HCl.The emulsion conditions,the technological factors such as ratios of oil to the internal aqueous phase and water to emulsion,and the extraction time etc.were investigated.
