Briquetting of Iron Bearing Materials

The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also de-airing these mixtures inside the vacuum chamber of the briquetting machine. So, briquetting process is developed to meet these demands. This process aims at recycle and reuse of the low grade iron ore and plant fines.

Iron Ore Briquette Processin

Iron briquetting increases the value of the loose bits of cast iron, as briquettes create an optimal charge in blast furnaces, where the iron is smelted and returned to useful production. Iron briquettes command a higher price at foundries than loose iron chips, as they yield metal in the smelting process.

Direct reduced iron Wikipedia

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)).
