1. Na-bentonite stage: In nature, the performance of calcium-based bentonite is worse than that of sodium-based bentonite. 2. Drying stage: Sodium-treated bentonite has higher moisture content and needs to be dried to a smaller moisture content. 3. Grinding stage: After drying, the bentonite is crushed, and the ore is lifted.

Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite's function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form a gel-like structure.
