fractions. Therefore, the agglomeration of manganese ore fines is one of effective ways to reduce the production costs of ferromanganese in China. Briquetting, sintering and pelletizing are the three main methods for the agglomeration of manganese ore fines [3−10]. Compared with sintering, pelletizing is an ideal process for manganese ore fines.

The iron and steel industries in India are vitally concerned with agglomeration of iron ore fines. Indian iron ores are relatively soft and friable; during mining and sizing processes around 30-40% fines (particles below 8 mm size) are generated. The ore washing plants also generate around 5 million tonnes of slimes per year.
