Abstract
This report describes recent progress at the Bureau of Mines Twin Cities Metallurgy Research Center on pilot plant development of roasting procedures for consuming ferrous scrap in a rotary kiln system. One phase of the research involves roasting lean iron ores of the nonmagnetic variety using a novel solid reagent, metallic iron in the form of ferrous scrap, as a means of reducing the ores to artificial magnetite. Another phase of the research concerns the treatment of ferrous scrap, such as discarded automobile hulks, in a rotary kiln without accompanying iron ore to yield coproducts of high-grade iron oxide and dense residual steel scrap of high purity. The former procedure is potentially of value to the iron mining industry and the latter process provides an effective method for the scrap processor to handle automobile hulks at industrial centers.
