A method of producing metal via the FFC process, comprising the steps of; (a) forming a blended feedstock powder comprising a plurality of discrete non-metallic particles and (b) Electrolytically reducing the blended feedstock powder so that the plurality of discrete non-metallic particles of the blended feedstock powder are reduced to a metallic powder comprising a plurality of discrete metallic particles. Step (a) involves providing a first non-metallic powder derived from a natural mineral or sand (ie rutile sand), the first non-metallic powder having a first overall composition, and mixing the first non-metallic powder with a second non-metallic powder having an overall composition different from the second non-metallic powder (ie ilmenite). The apparatus used may have a stainless steel cathode 20 with a carbon anode 30, located in a housing 40 which can comprise an electrolysis cell. The electrolyte 50 may comprise calcium chloride and calcium oxide. The powder may be arranged on the surface of the cathode 20. |
