The Whole Gold Mining Process
The Gold Mining Process
For example, many people picture gold nuggets when they think of gold mining, but pure nuggets gold are actually really rare in the mining industry. Gold is more commonly found in ore as microscopic particles. In most mining operations, every ton of ore only produces <10 grams of gold. In other words, 1 ton of ore is only .0005% gold.
