Optimising Mineral Recovery
We supply lime for the mining industry to improve mineral recovery, stabilise pH, and manage waste safely. Lime is a critical reagent in processes such as flotation, leaching, and effluent treatment. From gold and copper to alumina, nickel and cobalt, our solutions enable mining operations to improve efficiency and achieve environmental compliance.
Lime is a strategic reagent in both mineral processing and metallurgy. In mineral processing, it helps optimize flotation by controlling pH, thereby enhancing collector efficiency and promoting the selective separation of valuable minerals from impurities. In metallurgy, lime aids in the purification of leach solutions by precipitating dissolved impurities.
Additionally, lime plays a major role in reducing the environmental impact of mining operations by neutralizing acidic effluents before discharge.
Gold Mining
Used in BIOX, cyanidation, and tailings detoxification processes to enhance metal recovery and ensure operational safety.
Alumina Mining
Supports the Bayer process by precipitating impurities and reducing caustic soda use.
Nickel-Cobalt Mining
Controls pH in pressure acid leaching and neutralisation stages.
Copper-Cobalt
Lime precipitates impurities by increasing pH.
Other Mining
Used in uranium and lithium (spodumene) processing circuits to precipitate impurities such as Iron, aluminium and for pH control.
Benefits
- Enhances mineral recovery rates

Frequently Asked Questions (FAQ)
Why is lime important in mineral flotation?
Lime improves flotation by adjusting the pH, which enhances minerals collections efficiency and aids in the removal of impurities, thereby improving overall separation and recovery.
How does lime help in acid neutralization during mining?
Lime neutralizes acidic solutions after leaching operations before discharge to tailings, ensuring effective waste management and compliance with environmental regulations.
Can lime reduce environmental impact in mining operations?
Yes, lime stabilises tailings, detoxifies cyanide, and treats mine effluents, supporting sustainable mining and reducing pollution risks.
