Evaluation of New Processes for the Preparation of Iron by Gas/Solid Phase Systems

Abstract

All obvious possible processes for the manufacture of a shaped iron product from an iron bearing feed stock have been investigated and, from these, four have been selected as suitable for large scale production (order of 50,000 tons per year). Selection has been on the basis: 1) Technical feasibility 2) Crude economics 3) Information availability A review of the relevant literature has been made (see 9) and data has been extracted for the design calculations. Material balances have been made for the processes investigated and energy costs have been calculated where possible. All the routes investigated are shown on a Summary chart which also gives the approximate capital cost of each process.
