  • Gold Mining and Processing: Everything you Need to Know

    The Basics of Gold Mining and Processing. If the gold is located close to the surface its mined with openpit mining techniques. Gold thats located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces and then the sand grainsized pieces are mixed with a cyanide solution to create a watery mudlike mixture.
