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 LBMAs 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 LBMAs gold and silver lists.

But within the top echelons of the worlds 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.

Together these seven refinery groups have a combined gold refining capacity approaching a mammoth 5000 tonnes per year. And thats 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 Neuchtel, 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.

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.
