May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of sintered layer during sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in ore sintering. In this study, strengthening granulation using pre-pelletizing expand utilization ratio was proposed. The experiments conventional granulation, si...

The use of alternative raw materials is essential for establishing a circular economy in the mineral and ironmaking sectors. Therefore, this study investigates potential lime sludge as fluxing material during pelletization proposes an route usage waste. pellets were manufactured with different binary basicity values (CaO/SiO2) (0.15-0.45) bentonite (0.5-0.7 wt%) fixed carbon (0.5-1.1 contents. ...

Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reduc...
