What is iron ore pellet. Iron ore pellets are made by adding a small amount of additives to the fine ore powder (-200 mesh, that is, the ore powder with a particle size of less than 0.074mm accounts for more than 80%, and the specific surface area is more than 1500cm2/g), adding water to the pelletizer, relying on capillary force and mechanical …

Sponge Iron. Sponge iron, also known as direct-reduced iron (DRI), is a type of iron produced by reducing iron ore (typically in the form of pellets or lumps) using a reducing gas or solid reductant, such as coal.This reduction process occurs at a lower temperature compared to traditional iron smelting, resulting in a porous, sponge-like structure, hence …
