Iron ore sintering is the main process of fines agglomeration for ironmaking with relevant particulate matter and trace element emissions of integrated steel plants. Due to the high environmental and human health impacts caused by trace elements, legislations are becoming more stringent for regulating emissions of the trace elements.
