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 formcontained in the crystalline quartz. It's universally considered the ric…

Quartz gold ore is found in large veins of quartz, most commonly rose quartz and rainbow quartz. If the gold is on the surface of the rock it'll look like shiny yellow flecks or veins of gold. Iron oxide copper gold ore is found on the edges of granite or as long bands of dark rock flecked with gold.

Initially, bottle cyanidation tests are conducted on 200- to 500-gram charges of ground ore to determine the degree of gold extraction and reagent consumption. If the gold content of the ore is leachable at a relatively coarse grind, column percolation tests are made on ore crushed to various sizes, ranging from minus 2- to minus ¼-inch feed.

It is possible to detect gold with a specially designated metal detector. A prospecting detector can find gold as small as a half a grain. As the size of the gold becomes larger, gold nuggets can be located at deeper depths. A single grain nugget can be found at a depth of 1-2 inches.

Refractory Gold Processes. Gold can be leached and extracted/recovered in several ways. Even if you gold is "refractory" in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost.
