Specific Gravity is a measure of the density of a mineral. At times it is such a useful property that it is the only way to distinguish some minerals without laboratory or optical techniques. Gold (pictured) can easily be distinguished from "fool's gold" by specific gravity alone, although there are many other ways.

It is heavy (specific gravity of when pure) and is insoluble in all acids except aqua regia (a mixture of hydrochloric and nitric acids). Pyrite is harder than gold ( on Mohs scale) and is brittle. When struck with a hammer, it shatters. It is also relatively light (specific gravity of ). Pyrite frequently forms small cubes.

Gold is one of the heaviest minerals. When pure, it has a specific gravity of Due to its weight, it can be panned because the Gold sinks to the bottom. In addition, it can be easily separated from other substances due to the weight differences. Gold is also the most malleable and ductile substance known.

Jun 20, 2019 · But the ore is double refractory, meaning the gold is locked within the pyrite and contains a lot of carbon. Breaking the gold free requires both physical (ultrafine grinding, autoclaves) and chemical processes that are energyintensive and costly. In contrast, the simplest most inexpensive method is gravity recovery.
