Unveiling the Global Network: Who Supplies Sodium Cyanide to Mines?
Discover the key companies manufacturing and distributing this essential mining chemical worldwide.
Sodium cyanide (NaCN) is a vital chemical compound predominantly used in the mining industry, especially for the extraction of gold and silver from ore through a process called cyanidation or cyanide leaching. Given its effectiveness and cost-efficiency, it remains a cornerstone of precious metal recovery operations globally. However, due to its high toxicity, the production, transport, handling, and use of sodium cyanide are subject to strict regulations and safety protocols, often governed by the International Cyanide Management Code (ICMC). Identifying reliable and responsible suppliers is therefore crucial for mining companies. As of April 20, 2025, several key players dominate the global market for supplying sodium cyanide to mines.
Key Highlights
- Global Production Leaders: A few large multinational companies, including Orica (and its subsidiary Cyanco) and Draslovka, dominate global sodium cyanide production, particularly for the mining sector.
- Critical Role in Gold Mining: Sodium cyanide is the primary reagent used globally for leaching gold from ore, making its supply chain essential for the gold mining industry's viability.
- Emphasis on Safety and Compliance: Leading suppliers heavily emphasize safety, responsible handling, and adherence to the International Cyanide Management Code (ICMC) due to the chemical's hazardous nature.
Major Global Producers and Suppliers for Mining
The global supply of sodium cyanide for mining applications is concentrated among a handful of major manufacturers and distributors with extensive production capacities and sophisticated logistics networks.

Frequently Asked Questions (FAQ)
What is sodium cyanide primarily used for in mining?
Sodium cyanide is predominantly used in the mining industry for the extraction of gold and, to a lesser extent, silver from low-grade ores. The process, known as cyanide leaching or cyanidation, involves dissolving the precious metals into a dilute cyanide solution, allowing them to be separated from the crushed rock.
Why is safety and regulation so critical for sodium cyanide suppliers?
Sodium cyanide is highly toxic to humans and wildlife if ingested, inhaled, or absorbed through the skin. Accidental spills or improper handling during transport, storage, or use can have severe environmental and health consequences. Therefore, suppliers and users must adhere to strict safety protocols, regulations, and management practices, such as those outlined in the International Cyanide Management Code (ICMC), to minimize risks.
What is the International Cyanide Management Code (ICMC)?
The ICMC is a voluntary industry program for the gold mining industry and the producers and transporters of the cyanide used in gold mining. It aims to improve the management of cyanide during its life cycle, promote responsible handling, protect human health, and reduce the potential for environmental impacts. Many major mining companies, cyanide producers (like Orica/Cyanco), and transporters are signatories and undergo audits to certify their compliance.
What forms does sodium cyanide come in for mining use?
Sodium cyanide is typically supplied to mines in two main forms: solid and liquid. Solid sodium cyanide often comes as briquettes or pellets, which are easier to transport over long distances but require dissolution at the mine site. Liquid sodium cyanide is a solution (usually around 30% concentration) that is ready to use but requires specialized transport containers (like isotainers or rail tank cars) and has shorter transport range viability. Companies like Cyanco offer both forms, while others like Draslovka specialize in solid, and AnQore focuses on liquid.
Are there alternatives to using sodium cyanide in gold mining?
Yes, research and development into alternatives to cyanide for gold leaching are ongoing. Some alternatives include thiosulfate, thiourea, chlorine, and various biological leaching methods. However, cyanide leaching remains the dominant technology globally due to its high efficiency, relatively low cost, and well-understood chemistry, especially for complex or low-grade ores. The adoption of alternatives faces challenges related to cost, efficiency, environmental impact, and scalability.
