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.

How to Use Bentonite to Clarify Wine Winemaker's Academy

Bentonite is a unique clarifier in that it is the only one that may be used during fermentation as well as afterward. When you add bentonite at the beginning of fermentation you’re relying on the carbon dioxide bubbles that form to carry the bentonite up through the wine and, when the bubble pops, let it fall back down to the bottom.
