1. A method for separating a low volatility metal from a metal-containing feed stream, the method comprising:
applying solar energy to heat the metal-containing feed stream in the presence of a volatile metal halide in a heating zone to a first temperature to produce a first vapor mixture comprising a low volatility metal halide and a volatile metal, wherein the metal-containing feed stream is derived from black sands;
converting the first vapor mixture into the low volatility metal and the volatile metal halide;
condensing the low volatility metal to produce a first liquid comprising the low volatility metal; and
collecting the first liquid.
