Abstract

This paper gives an introduction to MTDATA, Phase Equilibrium Software from the National Physical Laboratory (NPL), and describes the latest advances in the development of a comprehensive database of thermodynamic parameters to underpin calculations of phase equilibria in large oxide, sulphide and fluoride systems of industrial interest. The database, MTOX, has been built over a period of thirty years based upon modelling work at NPL and funded by industrial partners in a project co-ordinated by Mineral Industry Research Organisation (MIRO). Applications drawn from the fields of modern copper scrap smelting, high temperature behaviour of BOS slags, flash smelting of nickel, electric furnace smelting of ilmenite and production of pure TiO2 via a low temperature molten salt route are discussed along with calculations to assess the impact of impurities on the uncertainty of fixed points used to realise the SI unit of temperature, the kelvin.
