Abstract
The disclosure relates to metal reduction processes, which comprise adding a mixture comprising at least one metal-containing material, at least one reducing agent, and at least one additive into a reactor, heating the reactor to a selected reduction temperature, moving the mixture through the reactor while stirring the mixture, allowing a reduction period to occur, and obtaining a resulting composition comprising at least one zero-valent metal and a residue. The disclosure also relates to metallurgical processes comprising the metal reduction process, and products made by the metal reduction process. The disclosure further relates to metal reduction apparatuses, as well as metal reduction systems and metallurgical systems comprising the metal reduction apparatuses.
