Mineral products are naturally occurring substances extracted from the earth and utilized in various industrial, commercial, and domestic applications. Here are details on some widely used mineral products:
1. Bentonite
- Bentonite Uses:
- Drilling mud in oil and gas exploration
- Binder in foundry sands
- Absorbent in cat litter
- Purification and clarification of liquids
- Carrier for pharmaceuticals and chemicals
- Properties:
- Highly absorbent clay
- Swells when wet
- Composed mainly of montmorillonite
- Types:
- Sodium bentonite (high swelling)
- Calcium bentonite (low swelling)
2. Calcium Carbonate (CaCO₃)
-
Calcium Carbonate Uses:
- Construction materials (cement, lime)
- Filler in plastics, paint, and rubber
- Dietary supplement and antacid
- Agricultural lime to neutralize acidic soils
- Paper industry as a whitening agent
- Properties:
- White, odorless powder or crystals
