The Process of Refining Gold: From Ore to Bullion
After the initial extraction, the gold is still in an impure form, often mixed with other metals such as silver, copper, and zinc. To achieve a higher level of purity, the gold must undergo further refining processes. The Refining Process: Purifying Gold. The refining process is crucial in transforming impure gold into high-quality bullion.

Pan Amalgamation and Variations
In order to speed up the process, Alvaro Alonso Barba invented the pa process, or pan amalgamation in the early 17th century. Instead of mixing salt, water, mercury, copper sulfate and ground up silver ore in a large outdoor patio, the pan process mixed these ingredients in several shallow copper pans heated with fire (instead of the sun).
