Abstract:
A method of extracting fat-soluble compounds from aqueous solutions comprising the steps of:providing an aqueous solution in which a fat-soluble compound is present; providing a bed of crystalline metallic ore particles held in a vessel; applying the aqueous solution to the bed of crystalline metallic ore particles substantially near the bottom of the bed at a rate sufficient to form and maintain a fluidized bed of crystalline metallic ore particles, wherein the fat-soluble compound is absorbed or adsorbed by the crystalline metallic ore particles to form crystalline-metallic-ore-fat-soluble-compound complex particles, wherein the bulk density of the particulate crystalline-metallic-ore-fat-soluble-compound complex is less than that of the particulate metallic ore, and wherein the fluidized bed forms an upper and a lower zone, the lower zone substantially comprising crystalline metallic ore particles and the upper zone substantially comprising crystalline-metallic-ore-fat-soluble-compound complex particles; collecting the crystalline-metallic-ore-fat-soluble-compound complex particles from the upper zone of the fluidized bed; providing a wash solution; contacting the wash solution with the crystalline-metallic-ore-fat-soluble-compound complex particles to desorb the fat-soluble compound; collecting the wash solution containing the fat-soluble compound; and isolating the fat-soluble compound from the wash solution.
