removal of phosphorous through roasting of ooliticiron

The present study is devoted to improvement of the leaching efficiency during phosphorous removal from high phosphorous gravity-magnetic concentrate. Before leaching the concentrate has been subjected to roasting with the addition of either Ca(OH)2 or CaO. The ooliticiron oreis roasted at 900°C for one hour. This reflects in reaction between alkaline earth additive and quartz

iron orecharacterisation during high temperature thermal

May 15, 2008· Ironmaking essentially involves different ways of combiningironores and energy sources to produce metalliciron. The thermal properties of theironores determine the amount of energy required forprocessing. Investigating and understanding these thermal properties is thus extremely important with respect to controlling the ironmaking processes

AbstractDuring production of calibrated (sized)ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised inironmaking due to its unfavourable granulometry, lowironcontent, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing dams are now considered as a threat due
