Gold ore combines with few elements. Because of this, it is found in nature in pure form and, to a limited extent, in gold ores. The gold ores that exist produce a relatively small percentage of all discovered gold. Nagyagite, calaverite, sylvanite, and krennerite are four examples of low-yield gold ore.

copper-gold ores (higher copper than gold values) the process route is typically flotation and smelting. In the latter case, gold credits are obtained from smelting the copper concentrates and if gold reports to the flotation tailings, they may also require cyanidation which can prove problematic with cyanide soluble copper.

Quartz is classically aligned with gold.The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz. It's universally considered the richest of the gold …
