oxygen is removed from iron ore in solid state. This procedure results in a spongy structure of the product M K Mitra 3 and R Deyiron ore fines cold briquetting process Chauffage Nanni. iron ore fines and coke fines with the addition of Portland cement as a binder and clay as a000 tons per year. Iron-carbon composite is produced by mixing iron ore fines & anthracite coal fines

which is suitable for being used as the raw material of a blast furnace or other direct reduction furnace. The method comprises the steps: (1) mixing hydrated iron ore and a flux to form ore/flux mixture in which fine grained materials are pressed into briquettes with the addition of moisture and/or another binder under high mechanical pressure. The briquettes may undergo further treatment or thermal processing before their use.On an average
