Use the gold panning method to separate the quartz and gold. Submerge the gold pan under water and rotate it. Lift the pan out of water while continuing to spin. Repeat this process until the material in the pan is gone. Due to their density, gold flakes and nuggets will collect around the lower ridge of the gold pan.

Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5. The differences in density make it easier to separate gold from other materials like silt and clay. Weight

The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5 ) (OH) 4) and gibbsite (Al (OH) 3 ). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.

Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.
