Quicklime, hydrated lime, and ground calcium carbonate play crucial roles in various applications within the mining industry.

Quicklime, also known as calcium oxide (CaO), finds application in the mining industry primarily for the process of ore flotation. In this method, quicklime is used to adjust the pH levels of the water, creating an alkaline environment that enhances the separation of valuable minerals from gangue materials. The addition of quicklime helps in the activation of certain minerals, promoting their hydrophobicity and facilitating their attachment to air bubbles during the flotation process.

Hydrated lime, or calcium hydroxide (Ca(OH)2), is employed in the mining industry for the treatment of acidic wastewater generated during mining operations. By neutralizing the acidic components in water, hydrated lime helps to prevent environmental damage and supports compliance with regulatory standards. Additionally, hydrated lime is utilized in the treatment of cyanide-containing wastewater, aiding in the detoxification process and reducing environmental hazards associated with mining activities.

Ground calcium carbonate (CaCO3) is commonly used as a filler material in the production of cement, providing improved strength and durability to construction materials used in mining infrastructure. Calcium carbonate is also utilized in the treatment of acid mine drainage, where it helps to neutralize acidic conditions and precipitate heavy metals, mitigating the environmental impact of mining activities.
