Use of adsorption colloidal flotation for sea water microelement extraction

The colloidal flotation is studied of copper, molybdenum and uranium from sea water, a hydrated iron oxide being used as a sorbent. Used as particle collectors are octadecanoic and indolyloleic acids, and as foamers-''Stearox 6''. Optimal conditions for the separation of copper, uranium and molybdenum from sea water have been found. The sorption isotherm equation is shown as being suitable for the description of the flotation process as regards these elements. The colloidal flotation process for the case under study is shown to obey the law of mass action in the pH range 0.5 to 0.7 and on the sorbent mass variation from 0.1 to 5.0 mg
