Extracting Gold | HowStuffWorks
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 gravellike material then enters rotating drums filled with steel balls.
How to Take the Impurities out of Gold | LEAFtv
Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.
The environmental impact of gold production
the gold from ore, carbon adsorption to extract the gold from the cyanide solution and electrolytic refining and chlorination to refine the gold. The LCA assessed production from both nonrefractory ores, which are relatively easy to treat, and refractory ores where the gold is 'lockedin' and requires more complex processing.
