11.25 Clay Processing
Bentonite - A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.Web

Polymers Applied in Pelletizing Binders
According to the production experience, for every 1 wt.% of bentonite added, the iron grade of pellet ore will decrease by about 0.6 wt.% [4], and the iron content will be reduced by about 7 kg/ton [5]. Therefore, achieving partial or total replacement of bentonite is an important development direction for metallurgical pellet binders.Web
