Abstract
The present disclosure generally relates to processes for the reduction of transition metals using alkali metals to produce reduced transition metals.
Claims27
A The process according to claim 26, wherein MT is Fe and the process is for the reduction of an iron metal oxide, the process comprising:
- (1) providing iron oxide having the formula FenOm, wherein each one of n and m is 1, 2, 3, 4, 5, 6 or 7;
- (2) contacting the iron oxide with sodium metal in a reactor, adjusting the temperature within the reactor to a first temperature in the range of 100° C. to 500° C., to induce a reaction according to scheme I:
- (3) separating between the Na2O and the Fe;
- (4) elevating the temperature of the separated Na2O to a second temperature, which is at least 50° C. higher than the first temperature, to induce a reaction according to scheme II:
- so that a net reaction, III, resulting from the reactions of schemes I and II, does not consume the sodium metal:

A process for the reduction of a transition metal oxide, the process comprising:
- (1) providing at least one transition metal oxide having the formula MTnOm, wherein each one of n and m is 1, 2, 3, 4, 5, 6 or 7, wherein MT is a first-row transition metal selected from:
- Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn;
- (2) contacting the at least one transition metal with an alkali metal in a reactor, adjusting the temperature within the reactor to a first temperature which is above the melting point of the alkali metal in the range of 100° C. to 500° C., to induce a reaction according to scheme I:
- wherein MA is Na or K;
- (3) separating between the MA2O and the MT;
- (4) elevating the temperature of the separated MA2O to a second temperature, which is at least 50° C. higher than the reduction temperature, to induce a reaction according to scheme II:
- so that a net reaction, III, resulting from the reactions of schemes I and II does not consume the alkali metal:
