The essential shape of the pyrite bodies found at the Cabin Branch Mine was that of a lens. Another scratch test can be done with copper. Pyrite and pyrrhotite often occur together creating an overlap in treatment methods. The crystal formations of pyrite are easy to distinguish as they form in cuboid shapes, often in close proximity with one another. Most gold particles found in streams have slightly rounded edges, but be careful - some crystalline gold specimens can display a crystal habit that is similar to pyrite. You can not do it with pyrite. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. Invisible gold is a type of gold ore that consists of micrometer sized blebs of native gold and structurally bound gold in iron sulfides, most commonly pyrite, arsenian pyrite and arsenopyrite. Miners who process gold ores will get free gold particles that can be melted into bars, but they also recover pyrite that has small amounts of gold within it. In powdered form is greenish black.

Also, gold has smooth edges, whereas pyrite has well-defined sharp edges. Mining companies most commonly seek primary gold, which is found in rock formations. The giant Carlin-type Au deposits (Nevada, USA) contain gold hosted in arsenic-rich iron sulfide (pyrite), but the processes controlling the sequestration of Au in these hydrothermal systems are poorly understood. Some theories suggest that the source of much of Earth’s gold comes from the explosion of distant supernovas. The mineral can take any shape when flattened and is easily scratched with a pocket knife. Also, high grade gold-pyrite flotation concentrates can be shipped to the smelter as is Knob Hill practice. Pyrite can sometimes be found in gold veins which has compounded the confusion. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. The most important use of pyrite is as an ore of gold. It is so common in the earth's crust that it is found in almost every possible environment, hence it has a vast number of forms and varieties. Fortunately these minerals often show good outer crystal shapes that are quite different. Pyrite is noticeably harder with a hardness of 6 on Mohs scale while gold is at a 3.
