·CFB applications iron ore processing • One Circored plant for direct reduction of iron ore was built using hydrogen as reductant Circored plant Trinidad 1996 • Two ilmenite roasters were built by Outotec Exxaro 2001 Empangeni South Africa; and Moma Sands 2005 Mozambique • Two iron ore preheaters were built by Outotec preheater for
·1 Iron ore supply and demand outline Types of iron ore Iron ores can be classified in different ways The most important has to do with the iron content In many cases ore with a total iron content of 60% to 63% or greater is regarded as high grade and ore with a lower iron content is regarded as low grade

segregated pellet bed profile provides benefits in plant throughput or energy savings depending on the plant strategy 1 Introduction The iron ore pellet holds a pivotal role in the ironmaking process enabling the utilization of high grade ore and the upgrading of low grade deposits [1] This process involves
What is ore sorting 2 Ore sorting is the separation of a target mineralogy ore or element from waste at an individual particle level The ore is sorted to remove waste and improve the efficiency and capacity of processing plant while increasing the grade Ore sorting is… Accurate > high recovery Fast > upto 5 000 particle per sec = high
·From the plant results an iron ore concentrate containing % Fe could be produced from a run of mine ore containing % Fe at a mass yield of % to the iron ore concentrate an iron recovery of % and a tailings grade of % Fe Magnetic separation is the most important method for upgrading low grade iron ores to high
Sponge Iron Plant Process Equipment 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 1200 °C
·beneficiate their ore is that the iron ore density distribution extends significantly beyond an SG of 4 which is the current limit of heavy liquid separations This makes it impossible to meaningfully predict the performance of jigs using partition curves and density distributions generated by heavy liquids
·Before the iron ore in the form of green pellet is entering the straight grate induration furnace it has been processed in different stages In the sorting plant the crude ore that has been extracted from the mine is separated from gangue and crushed down to smaller fractions Further on the crushed iron ore is entering the concentrating plant
