Process. Direct reduction processes can be divided roughly into two categories gas-based and coal-based. In both cases the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore concentrates pellets mill scale furnace dust etc.) in order to convert the ore to metallic iron without melting it (below 1 200 °C (2 190 °F)).
