Briquetting of Iron Bearing Materials

Briquetting of Iron Bearing Materials

The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also de-airing these mixtures inside the vacuum chamber of the briquetting machine. So, briquetting process is developed to meet these demands. This process aims at recycle and reuse of the low grade iron ore and plant fines.

As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation. Different sources of iron ore will respond differently to agglomeration, and process requirements will subsequently vary.

US3779782A Bentonite binder composition Google

A bentonite binder composition and method of preparation is disclosed. The binder composition is particularly useful for pelletizing iron ore fines. It is prepared by intimately combining and mixing wet bentonite in a stockpile with soda ash, the moisture in the wet bentonite bringing about reaction to form an improved binder after a suitable aging period.
