History
Switzerland dominates the investment gold market much like France leads the wine industry, refining approximately 65-75% of the world’s annual gold supply. Among Switzerland’s top refineries is Argor-Heraeus, a respected name on the international market known for excellence in gold processing. Thanks to a high-security environment, efficient logistics, and a robust financial system, Argor-Heraeus stands out for its high standards of quality and purity, making it a preferred choice for investors, banks, and financial institutions.
Argor-Heraeus gold bars, produced in Switzerland and accredited by the London Bullion Market Association (LBMA), are globally accepted and recognized. With a rich history and a steadfast commitment to quality, Argor-Heraeus ensures the integrity of each bar, offering investors reliable value and excellent liquidity on the international gold market.
Minted bars refer to the manufacturing process that is applied to create them. The process begins by heating gold material in a furnace until it turns to a molten slurry. During the heating process, all unwanted impurities in the slurry are removed until only molten gold of high purity is left, most often at around 99.99%. The molten gold is then poured into moulds, usually in the shape of large bars, where it cools and solidifies. The solid gold is then inserted into a mill that rolls the gold into panels with a uniform dimension. Afterwards, the gold panels are inserted into a blanking press that punches blanks out of the gold panels. The next step involves the weighing of each gold blank to ensure that it is neither underweight nor overweight and those that pass this test are then polished for them to obtain a shiny surface. The last stage involves the minting process where the gold blank is inserted into a minting press that presses its die with huge force to transfer the design from the die onto the gold blank. The result is a minted bar. The newly minted gold bar is then inspected before being sealed in a transparent tamper-proof protective package.
Argor-Heraeus is one of Switzerland’s and the world’s largest precious metals refineries. Argor-Heraeus is located near the Italian border, and also to the locations of two of Switzerland’s other giant precious metals refineries - Valcambi and PAMP.
