    THE BASICS OF GOLD MINING AND PROCESSINGWHAT IS GOLD USED FOR?WHERE IS GOLD FOUND?THE GOLD MINING PROCESSPlacer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, its mined with open pit mining techniques. Gold thats located farther below the surface isContact Us

    Extracting Gold HowStuffWorks

    How Gold Works. 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.
