With a total of 3 patents to his name, Aplan's work has had a lasting impact on industrial processes.
Latest Patents
One of Aplan's latest patents is titled "Process for the recovery of non-ferrous metal sulfides." This invention relates to a method of recovering non-ferrous metal sulfides from a metal ore. The process involves subjecting the metal ore, in the form of an aqueous pulp, to a froth flotation process in the presence of a flotation collector. The collector comprises a compound that corresponds to specific chemical formulas, where R¹ is an alkyl, aryl, or aralkyl group, which can be substituted with a halo or alkyl moiety. Another significant patent is "Process for beneficiating oil shale using froth flotation and selective." This process includes grinding the shale to fine particles in an aqueous medium, which contains both kerogen-rich and kerogen-poor portions. The method involves scrubbing the particles and separating them by selectively flocculating out a fraction, redispersing it, and reseparating using froth flotation, or vice versa. Additionally, it includes oil agglomerating and dewatering the kerogen-rich fraction.
