enrichment of iron ore can be achieved by separating unwanted components. This enrichment of iron ore represents a significant process step in steel production. During the concentration, most of the gangue is separated. This reduces transport costs and increases the production rate of the blast furnace and direct reduction plant. Since the iron ...

Iron Ore Pellets and Pelletizing Processes | PDF Scribd

Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 816 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the process of converting iron ore fines into Uniformed Sized ...

PDF Metso Pelletization Solutions

As highgrade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest cost.

Modern air pollution control for iron ore induration

The iron ore induration or pelletizing process emits particulates, sulfur dioxides (SOx), nitrogen oxides (NOx) and other pollutants depending on trace elements in the orebody and fuel. Typical emission levels for these compounds during induration will be outlined, and corresponding options for pollution control equipment described. Recent pellet plant construction in Sweden and the United ...
