METHOD AND AN ELECTRICALLY HEATED DEVICE FOR PRODUCING MOLTEN METAL FROM POWDERS OR LUMPS OF METAL OXIDES

摘要

This invention is related to a method and a process for producing metals by reducing and smelting metal oxides in two steps, the first of said steps comprising prereduction of a metal oxide charge. The prereduced metal oxide is transferred directly to the second step comprising final reduction of the prereduced metal oxide in an electrically heated smelting furnace with hydrocarbon containing reducing agent.
