Ask MGS: What are Gold Concentrates?
— Better known as "pay dirt," 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.
