Ensuring Gold's Lustre: A Look Inside Canada's Refineries

 Ensuring Gold's Lustre: A Look Inside Canada's Refineries

Refinery: Pure Gold from Raw Gold

The precious metal we love is purified from raw gold.

Gold must first be separated from rock and mineral particles. Many mechanical and chemical processes compress ore into a fine powder and dissolve gold. Filter and purify gold-rich fluid.

High-temperature smelting separates gold concentrate from other metals and contaminants. Moulds hold melted gold to manufacture dore bars.

Gold bars are refined. The bars are chemically and heat-purified over 99.5%. Global exchange gold bars, coins, and other objects are made from refined gold.

How Canadian Gold Refineries Ensure Quality and Value

Mines and investors provide refineries doré bars, gold dust, and scrap gold with impurities and other metals. The first stage is testing the gold for purity and refining techniques.

Melting/Chemical Processing: Gold is melted in a furnace to remove impurities and other metals. Adding nitric acid dissolves gold and filters out base metals. The solution is precipitated to separate gold from other compounds.

Purification: Electrolysis through gold solutions increases purity in refineries. Gold particles stick to negatively charged surfaces and fall off as pure gold. This continues until the gold is.9999 fine.

Check and Stamp: Fire assaying, spectrographic examination, and XRF scanning affirm the gold's .9999 purity. After approval, gold is moulded into bars and stamped with a serial number, purity, and refinery logo for worldwide commerce.

Canadian refineries make the world's best gold bullion and bars employing rigorous methods and cutting-edge technology. Their commitment to purity and quality keeps gold a valued store of value.
