Gold concentrates tend to be mostly iron, so they are also known as "black sands.". Gold concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less gold "concentrated" within.
