Apparatus and Methods For Purifying Lead

摘要

Disclosed is an exemplary method of purifying lead which includes the steps of placing lead and a fluoride salt blend in a container; forming a first fluid of molten lead at a first temperature; forming a second fluid of the molten fluoride salt blend at a second temperature higher than the first temperature; mixing the first fluid and the second fluid together; separating the two fluids; solidifying the molten fluoride salt blend at a temperature above a melting point of the lead; and removing the molten lead from the container. In certain exemplary methods the molten lead is removed from the container by decanting. In still other exemplary methods the molten salt blend is a Lewis base fluoride eutectic salt blend, and in yet other exemplary methods the molten salt blend contains sodium fluoride, lithium fluoride, and potassium fluoride.

主权项

1. A coolant purification device, comprising:
a container thermally connected with a heat source; an inlet configured to disperse molten lead into a first end of the container; a molten fluoride salt blend within the container interior; an outlet configured to discharge the molten lead from a second end of the container; and a tortuous path passing through the molten salt blend and connecting the inlet to the outlet.
