The World’s largest Precious Metals Refineries

There are many precious metals refineries throughout the world, some local to their domestic markets, and some international, even global in scale. Many, but by no means all, of these refineries are on the Good Delivery Lists of gold and/or silver. These lists are maintained by the London Bullion Market Association (LBMA) and they identify accredited refineries of large (wholesale) gold and silver bars that continue to meet rigorous proficient standards of refining and assaying, and that are, at the same time, financial viable and stable companies. Currently, there are 71 refiners on the LBMA’s gold Good Delivery List and 81 refiners on its silver Good Delivery List, or which just over 50 of these refineries are accredited to both the LBMA’s gold and silver lists.

But within the top echelons of the world’s precious metals refineries, a number of names stand out due to their sheer scale and pedigree, as well as their global brand recognition in the production of a wide range of investment grade gold and silver bullion bars. These names include PAMP, Argor-Heraeus, Metalor Technologies, Heraeus, Valcambi, Tanaka Kikinzoku Kogyo, and Rand Refinery.

5000 Tonnes of Gold

Together these seven refinery groups have a combined gold refining capacity approaching a mammoth 5000 tonnes per year. And that’s not even taking into account their refining capacity for other precious metals such as silver and platinum. Valcambi has a gold refining capacity of 1600 tonnes per annum, Metalor 800 tonnes, Heraeus 400 to 500 tonnes, PAMP over 450 tonnes, Argor-Heraeus over 400 tonnes, Tanaka 500 tonnes, and Rand Refinery 600 tonnes.

Notably four of these refineries are based in the gold refining powerhouse of Switzerland, of which three, PAMP, Valcambi and Argor-Heraeus, are clustered literally within a few kilometres from each other in the golden triangle of Swiss refineries centred within the very south of the Swiss canton of Ticino near the Swiss-Italian border. Metalor Technologies is the exception, as its Swiss headquarters facility is based in Neuchâtel, in the north-west of Switzerland. Of the non-Swiss refineries, Heraeus, Tanaka and Rand Refinery, these are headquartered in Germany, Japan and South Africa, respectively.

International in Scale and Ownership

Although three of the four giant Swiss refineries have historically each been owned by a Swiss bank, and although groups such as Heraeus and Tanaka are still privately owned and controlled by founding shareholders, its important to note that none of these giant refineries are purely local concerns, so their headquarters locations are to some extent a secondary concern. From operating facilities, to metal supplier networks, to customer bases, all of these refineries are now absolutely global in nature.

For example, Metalor operates four precious metals refineries globally, in Switzerland, Hong Kong, Singapore and Massachusetts (US). Heraeus runs gold refining and gold bar production facilities in Hanau (Germany), Hong Kong, and Newark (US). In addition to its Swiss refinery, PAMP, part of the Geneva-based MKS PAMP group, runs a joint venture refinery in New Delhi, in conjunction with MMTC, a large state-owned Indian trading company.

In many cases, the ownership of these refineries is international and cross-border in nature, and increasingly so over the last few years. Agor-Heraeus is owned by the Austrian Mint and two German entities Commerzbank and Hereaus. In 2015, Valcambi was acquired by Indian jewellery producer Rajesh Exports, with one of the selling shareholders being US-based gold mining giant Newmont. Indeed, just last month, Tanaka announced the acquisition of Metalor Technologies, a development which has initiated an upcoming major Japanese - Swiss precious metals refinery combination. Metalor was already international in ownership, as its controlling shareholders are French and Belgian private equity companies. While Rand Refinery of South Africa is  exclusively owned by five of the largest South African gold mining companies, some of these owners, such as Anglogold Ashanti and Goldfields, are vast international concerns. Rand Refinery has also increasingly had to cast its new wider for sourcing gold to process in its refinery as South African gold mining output has declined. Rand Refinery now refines over 75% of the gold mined on the African continent (excluding South Africa), and is also increasingly tapping into gold mining output from the US and Asia.

The World's Refinery Referees

Another indicator of the esteem within which these select refineries are held is their membership of the exclusively small panels of good delivery list referees which have been appointed to run the LBMA’s good delivery lists, and similar good delivery lists maintained by the London Platinum and Palladium Market (LPPM) for platinum and palladium bars.

The LBMA’s good delivery referee panel is a five refinery member panel made up of Argor-Heraeus, Metalor Technologies, PAMP, Rand Refinery and Tanaka Kikinzoku Kogyo. The LPPM’s referee panel also comprises five refiner members, namely Metalor Technologies, PAMP, Valcambi, Tanaka Kikinzoku Kogyo and platinum specialist Johnson Matthey. So not only are these refineries listed on these LBMA and LPPM good delivery lists, they actually help run the entire set of good delivery standards and processes. With the upcoming acquisition of Metalor by Tanaka, these LBMA and LPPM referee lists may need some adjustment, since Tanaka and Metalor are members of both referee panels.

Overwhelmingly, the gold and silver bars of these refiners are all also accepted as good delivery for the COMEX gold 100 oz and gold kilo futures contracts, the gold contracts of the Tokyo Commodity Exchange (TOCOM), the Dubai Good Delivery gold list maintained by the Dubai Multi Commodities Centre (DMCC), and the good delivery standards of the Shanghai Gold Exchange.

Investment bullion bars

Although all of these precious metals refineries, to various extents, supply semi-fabricated precious metals, alloys and industrial precious metals suppliers to a diverse set of industrial and jewellery sector clients, it is perhaps the investment grade bullion products of these giant refiners that they are best known to a global audience.

PAMP fabricates a vast range of cast and minted gold and silver bars which are extremely popular across Asia and the Middle East, in fact, the premier brand in those regions. Valcambi manufactures a wide range of gold, silver and platinum / palladium investment bars, as well as precious metal coins and medals, and has become well-known as the international supplier of Combibars. Heraeus, Metalor and Argor-Heraeus produce a wide selection of gold and silver bars ranging from large wholesale (good delivery) bars through to smaller cast and minted gold and silver bars. Tanaka’s gold bars dominate the Japanese market and notably, Tanaka is also the sole distributor in Japan of gold and silver bullion Maple Leafs coins from the Royal Canadian Mint and gold and platinum Philharmonic coins from the Austrian Mint. Tanaka's acquisition of Metalor will be interesting in terms of how the combined group markets and distributes its investment bullion products going forward.

It's also not widely appreciated that Rand Refinery has refined over 50,000 tonnes of gold since it first opened in 1921, which is a staggering nearly one-third of all the gold ever mined. Rand Refinery large gold bars are held widely by central banks across the world. Rand Refinery’s flagship gold bullion Krugerrand coin is also held very widely, with over 60 million Krugerrands minted since 1967.

This article has not touched on the Perth Mint, Royal Canadian Mint or Royal Mint, which its important to remember, each operates its own precious metals refinery facilities in addition to being a sovereign national mint.

In summary, the seven refineries featured above are truly giants of the industry, and their longevity and customer trust attest to the authenticity and quality of their investment bullion products.
