Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. InHow Gold Plating is Done, Step by Step - Analyzing Metals,This extends the life of the bright gold plating. Step 5: Rinse Again. The piece is rinsed thoroughly with water to remove any cleaning agents. Step 6: Base Coat. If a base coat below gold is used, it is usually nickel.There can be many layers of plating done on one particular piece. For example a gold-plated silver article is usually a silver substrate with layers of copper, nickel, and gold,major steps in the process of mining and refining gold,,22/04/2013· Comminution is the first step in processing and involves the breaking up of the ore, »More detailed.
