The sintering of fine ores can also be a polluting process, and mills under environmental constraints may favor direct-charge ore such as lumps or pellets. Chinas 2016 update to its Environmental Protection Law enforces stricter caps on industrial pollution, and has increased the appetite for higher purity ores.
Pre-reduction of fine iron ore at low temperatures was studied with single factor and orthogonal experiments. The effects of ratio of gas to solid, reaction time, temperature of furnace, particle size and kind of reducing agent on the reduction degree of fine iron ore were examined respectively. The process parameters were optimized and the behavior of carbon deposition
