    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, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is.
