Iron Pellets
Iron Pellets
Basetrade Global sources and supplies high-quality, DRI-grade iron pellets which have a minimum Fe content of 65 per cent and above.
Iron ore is upgraded to high iron content through a beneficiation process to obtain powder like iron concentrate. The concentrate is then palletised into iron pellets in order to feed a blast furnace or the shaft furnace of a direct reduced iron (DRI) plant. Basetrade is primarily focused on the higher grade iron pellets used as feedstock in shaft furnace of DRI plants.

During the process of pelletising iron concentrate, the soft raw material is rolled into balls on large constantly revolving wheels. The are fired in a rotary kiln, which sinters the particles into small, hard spheres that are typically 8mm to 18mm in size and contain 64% Fe and above. The remainder of a typical iron pellet is compose of refining materials such as limestone, dolostone and olivine, and bentonite which is used as a binding agent.
