Other iron ore sintering processes use machines that take crushed iron ore and mix it with water and other substances, known as fluxes, prior to igniting the mixture. Electricity is conducted through the mixture, and its surface is ignited to help form an agglomerate. Dust from the iron ore, as well as iron particles that do not meet size requirements, are recirculated through the machine with ...
