Fine Ground Quicklime
Calcium Oxide - CaO (0/3 mm)
Tamax Ventures supplies Carmeuse Fine Ground Quicklime (Calcium Oxide, CaO) to the West African mining sector, specifically engineered for high-reactivity gold cyanidation loops and structural soil stabilization.
Highly reactive Calcium Oxide. Essential for gold mining and steel manufacturing.
1. Product Description
Fine Ground Carmeuse Quicklime (0/3 mm) is a highly reactive, finely ground Calcium Oxide (CaO) in the form of a white, dry, odorless powder with a controlled particle size distribution below 3.00 mm.
Key Applications
Gold Mining & Metallurgy
Highly utilized in chemical cyanidation extraction loops, flotation pH control, and slag conditioning/refining.
Steel Manufacturing
Functions as an active fluxing agent to separate impurities in blast furnaces.
Soil Stabilization
Highly effective for drying, modifying, and chemically stabilizing clay-heavy structural sub-soils for roads, airports, and structural foundations.
Chemical Synthesis
Used as an active dehydrating agent, neutralizing compound, and industrial chemical feedstock.
Safety Warning
Severe Chemical & Burn Hazard: Calcium oxide reacts highly exothermically (generating intense heat) upon contact with water or sweat. This reaction can ignite flammable materials and cause severe chemical skin and eye burns.
Packing & Storage
Packaging Options:
- 25kg moisture-barrier sealed paper bags.
- 1-ton high-strength woven jumbo bags with hermetic PE liners.
- Loose bulk delivery via specialized dry pneumatic tankers.
Storage Guidelines:
Store in dry, enclosed silos or protected, airtight warehouses. Because quicklime absorbs moisture from the air and reacts exothermically, it must be kept strictly away from humidity, damp air, and acidic chemicals.
