Research Progress of Bentonite Used in Metallurgical Pellets in China and Abroad

In order to understand the research progress of bentonite binder used in metallurgical pellets in China and abroad, basing on a large number of literature, the resource background, crystal structure, mineral composition, physical and chemical properties of bentonite as well as the performance index and evaluation method of bentonite used in metallurgical pellets were introduced firstly. And then the relationship between bentonite properties and pellet properties, the preparation status of bentonite binder and the action mechanism of its when used in metallurgical pellets were summarized to provide reference for related researches.
