The Corex process

Abstract

The commissioning of Iscor's Corex direct reduction plant for producing iron from low-grade coal at Pretoria is described and the results obtained are reported, with details of production rates, product quality, raw materials tested (including the coal requirements) and problems encountered. Costs are compared qualitatively with those of the coke oven-blast furnace route. Some basic aspects of the process, its advantages and future prospects are discussed.
