Gold Concentrates


Gold concentrates are sourced in two different ways. The first is through gold panning (or other techniques that use gravity separation). When panning for gold, the objective is to separate the particles of dirt from the heavy particles of gold. In most cases however, gold is not the only heavy material in the pan. This end result of the panning process is the gold concentrates – which must be sifted through manually to extract the bits of gold. 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. The pay dirt bundled with panning kits or sold as souvenirs in gold rush towns usually comes from this grinding method.
