Gold Refining From Gold Ore to Doré World Gold Council

***COPPER REMAINS IN GOLD impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold

From Ore to Finished Product Copper

Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man. Today, copper's uses have expanded to include heating, cooling and refrigeration

How Gold Electroplating Is Done Sharretts Plating Company

In all gold plating, the part is polished and cleaned as thoroughly as possible before the electroplating process starts. Gold plating will look uneven and smudged if the surface is dirty, oily, scratched or otherwise damaged. Modern electroplating begins with the creation of a metal salt using the plating metal, typically gold or silver. These salts are formed when an acid and a base combine
