choice for high-capacity concentrate dewatering with the lowest operating costs. In one case, this meant increasing throughput to more than 500 t/h per machine, with half the total footprint of traditional solutions. In a different brownfield project, the result was the world’s largest hyperbaric disc filter in iron ore production, with a

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)).
