roasting of iron ore for ugradation

Wheniron oresareroastedat temperatures above about 1500° F., the magnetite mineral contained in theoreoxidizes rapidly enough to act as a significant source of heat for the process. The fuel value of magnetite burned in this way is about 7000 BTU/lb. When magnetite is burned, hematite is produced.

    Best results were obtained at 800°C for 30 min using 10% coal in the charge. Using these conditions a product containing 66.6% Fe was produced at 90.4% recovery. The roasted samples were characterised by XRD which confirms the hematite to magnetite transformation and by SEM which highlighted the porous nature of the upgraded ore.

    Ore roasting can be accomplished in many ways. The simplest way is to build a large wood fire on the ground or in a shallow pit and toss the ore on top. The problems with this are that it is near impossible to guarantee that everything gets well roasted and when you’re done you just have a pile of ore and ash that is difficult to separate.
