METHOD FOR DIRECT METAL MAKING BY MICROWAVE ENERGY

摘要

A method for the direct preparation of metal from metal-containing material comprising providing metal-containing material and a reducing agent, mixing the metal-containing material with the reducing agent to form a mixture charging the mixure by an appropriate method except flowing a stream of small particles into a container, heating the mixture with minimal contamination by applying microwave energy to the mixture until molten metal is released from the metal-containing material, accumulating the molten metal by gravity at the bottom of the container, and discharging the metal from the container.
