The FINEX is the latest addition and an optimized fineore smelting reduction (SR) iron making process based on the direct use of the coal and iron ore fines. FINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets.
By the DAPS process, coal is dried in a fluidizedbed dryer, fine coal grains mm or less in size are separated from coarser grains by the gas flow, collected by a cyclone separator, formed into agglomerate by a roll compactor, mixed with the coarser grains, and charged into coke ovens. The mass fraction of the fine grains is approximately 30%.
