    Abstract: A used investment casting wax composition containing a filler and/or a residue after a wax component is removed from the composition is dissolved or dispersed into an organic solvent. The mixture is separated into a dissolved wax fraction and a wax-containing solids fraction. The organic solvent in the dissolved wax fraction is removed to recover a wax component, while the wax component and the organic solvent in the wax-containing solids fraction are removed to recover a crude filler. The crude filler is washed with water and/or an aqueous alkaline solution to recover a high-purity filler. A reclaimed investment casting wax thus obtainable is less degraded by heat.

    Abstract: For separating wax particles and/or water droplets from a hydrocarbon mixture boiling in the lubricating oil range, net positive or net negative free excess electric charge is introduced, e.g. by a charge injector (44), into the wax/water-laden oil mixture. The oil is brought into contact with at least one collector surface, which can be provided by a bed of closely packed beads (33) in a separation vessel (6) or, for separating wax particles, a rotating collector drum (61). The introduced charge attaches itself to the wax particles/water droplets and at the same time causes an induced electric field to be set up within the oil mixture. The electrophoretic effect produced by the interaction between the charge and the induced field causes the wax/water to collect on the collector surface and accumulate there, for separation from the oil mixture.
