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.Web

Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.Web

Oxalic acid, or "Iron-Out", is great for removing iron oxide stains from stones, for instance. It's often the preferred cleaning method for quartz and chalcedony specimens with orange crustings of rust after being cleaned. It can weaken some iron-based minerals if you're looking to separate crystal types. Use the weakest acid you can.Web
