11.25 Clay Processing US EPA

2015-9-10  In some cases, the crude clay is weathered for 6 to 12 months, depending on the type of fire clay. Freezing and thawing break the material up, resulting in smaller particles and improved plasticity. The material then is crushed and ground. At this stage in the process, the clay has a moisture content of 10 to 15 percent.

Bleaching Clay Industry Trends & Opportunities

The U.S. and China are the world largest bentonite producers and accounted for 50% to 60% of the overall supply in 2015. Crude oil refining includes degumming, neutralization, bleaching, deodorization, and further refining. Bleaching clay is widely used in the edible oil and fat industry in the decolorizing and refining process. Crude oil is bleached with natural or acid-activated clay minerals to absorb coloring
