The DRI fine is separated using screens in the process of transmission from the direct reduction plant to the steel (smelter) plant. Then, small amounts of lime and silicate glue are added and the mix is compressed into briquettes in the briquetting machine. Due to their high rate of metallization and a proper weight, briquettes are used in the electric arc furnace to help with the melting.
