Almost all gold produced in the world was transited physically through Switzerland during the 2011, the data from the U.S. Geological Survey showed Friday. Over 2600 metric tons, out of the 2700 tons which were mined in the world last year, with a total value of $103 billion were refined in Switzerland, as it is the only country in the world, where gold purity is regulated by law.
"A refinery produces not just gold bars, but semi-finished products, like coins and medals, which require a high degree of precision. Switzerland has always maintained itself at the top as regards quality and there is no reason why that should change now."
