Removal of impurities from the iron ore is done prior to subsequent processing in pelletizing plants and direct-reduction plants. Otherwise, the impurities will simply pass on to the downstream production steps, resulting in higher energy requirements to melt the increased quantities of slag (where the impurities generally tend to concentrate).

Preparation: Before smelting iron, the ore often gets smashed and ground up to make it work better with the reducing agent. This process increases the surface area of the ore, making it more effective when it comes into contact with the reducing agent. In many cases, the ore contains impurities that must be removed for a successful smelting ...
