High costs and environmental problems associated with making iron and steel in the United States have prompted the development of alternate technologies to the blast furnace. These technologies include the Rapid-Rate Reactor (RRR) developed by the U.S. Bureau of Mines. Theoretical calculations were made to determine the feasibility of treating both ferrous and non-ferrous metal oxides and waste products, such as electric-arc-furnace (EAF) dust in a simulated high temperature reactor based on the rapid-rate reactor data. The results showed high vapor pressures of zinc and lead (>10 bars) with low liquid yields of 39 and 67% depositing in the lower temperature regions of thereactor. The rapid-rate reduction system has a low capital cost, but has 4 times the operating costs versus the iron blast furnace and Horsehead Flame Reactor due to high fuel consumption. The description of the rapid-rate reactor and feasibility of treating non-ferrous metals are given.
