Pelletization Using Humic Substance-based Binder

ABSTRACT Humic substances exist widely in lignite coal as high molecular weight organic molecules. They can be used as binders in iron ore pelletization mostly in the form of salt, such as sodium humate and amine humate via extraction from lignite coal. It is worth determining if lignite can be used as a binder without extraction. As a …

Pelletization of fine coals. Final report

Pelletization, a model of agglomerating fine particles can alleviate some of these problems. This study was undertaken to ascertain the process and economic feasibility of the pelletization of fine coals. Laboratory pelletization studies were carried out on a number of coal samples of different ranks and of different geographical origins.

Iron Ore Pelletizing Process: An Overview

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
