At [META CHEMICALS SUPPLIER], we are dedicated to providing the mining industry with high-quality mineral chemicals that ensure maximum efficiency, safety, and sustainability in gold extraction. Gold leaching is a crucial stage in ore processing, where the right chemical agents directly influence recovery rates, processing speed, and environmental compliance. By combining trusted solutions with innovative alternatives, we deliver a complete portfolio of leaching reagents tailored to diverse mining operations worldwide.
Our Gold Leaching Chemicals
1. Cyanide-Based Leaching Agents
- Sodium Cyanide (NaCN): The industry standard for gold dissolution in heap leaching, tank leaching, and carbon-in-pulp (CIP/CIL) systems. Known for high efficiency but requires careful handling due to toxicity.
- Calcium Cyanide (Ca(CN)₂): Offers similar performance to sodium cyanide with additional stability in storage and transport.
2. Cyanide-Free & Eco-Friendly Alternatives
- Thiosulfate (Na₂S₂O₃): Highly effective for ores where cyanide use is limited, offering safer environmental impact.
- Thiourea (CS(NH₂)₂): Fast-acting lixiviant, suitable for certain refractory ores but less stable in large-scale applications.
- Halogen-Based Solutions (Chlorine, Bromine, Iodine): Strong leaching agents with high efficiency, though less common due to cost.
- Glycine-Based Leaching Agents: A promising green alternative that selectively dissolves gold with low toxicity, aligning with modern sustainability standards.
3. Supporting Chemicals & Reagents
- Lime (CaO): Controls pH levels, stabilizes cyanide solutions, and reduces cyanide loss by preventing volatilization.
- Activated Carbon: Essential in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes for gold adsorption after dissolution.
- Oxidizing Agents (Oxygen, Hydrogen Peroxide, Lead Nitrate): Improve leaching kinetics and recovery rates, especially in refractory ores containing sulfides.
- Detoxification Reagents (SO₂/Air Systems, Caro’s Acid, Hydrogen Peroxide): Applied to neutralize cyanide residues in tailings, ensuring compliance with environmental regulations.
Why Choose Us
By sourcing only the finest-quality chemicals and ensuring strict quality control, [META CHEMICALS SUPPLIER] enables mining operations to achieve higher recovery rates, faster dissolution, and reduced operational risks. Our solutions support both traditional cyanide-based methods and modern eco-friendly alternatives, allowing clients to balance efficiency with sustainability. We are committed to supplying not just chemicals but also technical guidance and after-sales support to ensure safe, efficient, and environmentally responsible gold leaching.
we pride ourselves on being a trusted supplier of high-quality mineral chemicals that power the gold mining industry. Gold leaching is one of the most crucial steps in the extraction process, and the quality of chemicals used can directly determine recovery rates, processing efficiency, and environmental compliance. Our mission is to provide mining operations with reliable, effective, and sustainable leaching solutions that maximize gold recovery while ensuring safety and minimizing ecological impact.
Cyanide-based leaching agents, such as sodium cyanide and calcium cyanide, remain the most widely used chemicals in gold extraction due to their proven efficiency in dissolving gold from ores. They are essential in processes like heap leaching, tank leaching, carbon-in-pulp (CIP), and carbon-in-leach (CIL), where large-scale operations depend on consistent and effective chemical performance. While cyanide remains the backbone of modern gold leaching, its handling requires strict safety protocols, and our products are manufactured and supplied under rigorous standards to guarantee both performance and safe usage.
Recognizing the growing demand for safer and more environmentally friendly alternatives, we also provide advanced cyanide-free lixiviants that deliver competitive recovery rates with lower environmental risks. Thiosulfate and thiourea are particularly useful for processing ores where cyanide leaching is less effective, while halogen-based lixiviants such as chlorine, bromine, and iodine offer high dissolution power for specific applications. More recently, glycine-based leaching has emerged as a promising green solution, offering selective gold recovery with low toxicity and strong alignment with modern sustainability goals. By supplying these innovative alternatives, we help our clients meet environmental regulations and adopt greener mining practices without compromising on efficiency.
In addition to primary leaching agents, we supply a range of supporting chemicals that enhance the leaching process. Lime is critical in maintaining the optimal alkaline pH required for cyanide stability, preventing solution losses and improving overall process control. Activated carbon plays a vital role in gold adsorption during CIP and CIL processes, ensuring effective recovery after dissolution. We also offer oxidizing agents such as oxygen, hydrogen peroxide, and lead nitrate, which improve reaction kinetics and increase gold recovery rates, especially in refractory ores containing sulfides. To support environmental compliance, we provide detoxification chemicals that neutralize residual cyanide in tailings before disposal, ensuring safe waste management and adherence to regulatory standards.
