Abstract: Disclosed is a separator for separating a meltable solid from a mixture with other solids. The separator has a tank for holding a fluid; a container at least partially inside the tank, made at least in part of a screen through which the fluid can pass and melted solids can flow, but through which the unmelted solid material will not flow; and a heater for heating the fluid above the melting point of the meltable solids. Also disclosed is a method of separating a meltable solid from a mixture with other solids. The mixture of solids is placed in the container of the separator and the fluid is heated to a temperature above the melting point of the meltable solid, whereby the meltable solid flows through the screen out of the container, while the other solids remain within the container.
