摘要： A method of producing a non-metallic feedstock powder suitable for reduction to metal comprises the steps of combining a liquid with solid metal oxide particles to form a mixture, subjecting the mixture to high-shear mixing to form a liquid suspension of metal oxide and the liquid, and drying the liquid suspension using a fluidised-bed spray-granulation process to grow a plurality particles to form the non-metallic feedstock powder. The method allows feedstock powders to be grown to desired particle sizes. The method allows production of feedstock powders having controlled compositions.

摘要： A method of producing metallic powder comprises steps of arranging a volume of feedstock comprising a plurality of non-metallic particles within an electrolysis cell, causing a molten salt to flow through the volume of feedstock, and applying a potential between a cathode and an anode such that the feedstock is reduced to metal. In preferred embodiments the feedstock is a plurality of discrete powder particles and these particles are reduced to a corresponding plurality of discrete metallic particles. In advantageous embodiments, the feedstock may be sand.
