Abstract
A method for the direct preparation of metal from metal containing ore by applying microwaves, alone or in combination with other heating means, to extract metal from masses made by forming a powder of ore and an optional reducing agent. The method minimizes the expenditure of energy used to refine the metal, the level of contamination introduced into the metal, and the production of environmental pollutants.
Claims17
A method for the direct preparation of metal from metal containing ore comprising providing metal containing ore and a reducing agent, concentrating said ore into fine particles, mixing said fine particles with said reducing agent to form a mixture, agglomerating said mixture into a plurality of masses, charging said masses into a container, heating said mixture with minimal contamination by applying microwave energy to said mixture until molten metal is released from said metal containing ore, accumulating said molten metal by gravity at the bottom of said container, and discharging said metal from said container.
