Abstract
A methodology for selection of ironmaking technology for specific site conditions has been developed and used for practical applications. The methodology is based on a two stage predetermined process of technical and economic analysis to screen and eliminate the unfavourable technologies. The first stage includes an evaluation of all available data applied to specific ironmaking technologies with the selection of up to three of the best technologies based on risk analysis, simple pay back period, factored capital cost analysis and operating cost estimates. The second stage includes a detailed financial analysis to select the best applicable technology. Application of this methodology and principles has facilitated Hatch’s recommendation and/or rejection of available ironmaking technologies for several global iron and steel companies to meet their specific needs.
