Extracting Gold HowStuffWorks

Removing the gold bearing rock from the ground is just the first step. To isolate pure gold,panies useplex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel like material then enters rotating drums filled with

Ask MGS: What are Gold Concentrates? Manhattan Gold Silver

While gold concentrates sounds like one of golds chemically modified derivatives, it is in fact, natural. 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
