The Importance of Gold Refining

Gold refining is a critical step in the precious metals supply chain, transforming unrefined gold, often mixed with other metals and impurities, into a highly pure product. Raw gold from mines typically exists as ore, concentrates, or doré bars (a semi-pure alloy of gold and silver). The refining process is essential to extract the gold and bring it to a standard purity level required for various applications, such as investment bullion, jewellery manufacturing, electronics, and dentistry. High purity levels, often expressed as ‘finesse’ or parts per thousand (e.g., 999.9 fine gold), are crucial for maintaining the intrinsic value and usability of the metal.

South Africa, with its historically rich gold reserves, has developed world-class refining capabilities. These refineries not only process domestically mined gold but also often handle materials from other African nations and international sources. The technology employed is advanced, utilizing processes like the Miller chlorination process or the Wohlwill electrolytic process to achieve exceptional purity. Beyond the technical aspects, responsible refineries also focus on environmental stewardship, minimizing waste and emissions, and ensuring ethical sourcing practices throughout their operations. This commitment is vital for maintaining trust and compliance in the global market.

South Africa’s Gold Mining Legacy

South Africa has long been synonymous with gold. For over a century, it was the world’s largest gold producer, and while its output has decreased in recent decades, it remains a significant player. The Witwatersrand Basin, in particular, holds some of the richest gold deposits ever discovered. This extensive mining history has necessitated the development of robust infrastructure, including sophisticated refining operations. The expertise gained over generations in mining and metallurgy has positioned South African refineries at the forefront of the industry, capable of handling large volumes and complex processing challenges.

Key Processes in Gold Refining

The primary methods used in modern gold refining include:

1. Miller Process: This is a widely used method for preliminary refining. Chlorine gas is bubbled through molten doré metal. The chlorine reacts with base metals (like copper, zinc, silver) forming chlorides, which are removed, leaving behind gold of approximately 99.5% purity. This process is efficient for removing base metals but less effective for separating silver.

2. Wohlwill Process: For achieving very high purities (99.99% or higher), the Wohlwill process is employed. This is an electrolytic method where impure gold anodes are dissolved in an electrolyte solution, and pure gold plates onto the cathodes. Silver and platinum group metals tend to remain in the anode slime, allowing for their recovery.

3. Aqua Regia Process: This method uses a mixture of nitric and hydrochloric acids to dissolve gold. It is effective for dissolving gold from complex ores or electronic scrap but requires careful handling due to the corrosive nature of the acids.

By-product Recovery

Gold refining processes often yield valuable by-products, such as silver, platinum, palladium, and rhodium. Modern refineries are equipped to recover these precious metals from the refining slimes and solutions, adding significant economic value and contributing to a more sustainable use of resources. The efficient recovery of these associated metals is a hallmark of advanced refining operations.
