The main sulfide mineral associated with tin and the biggest matrix for tin ore. It is typically found in igneous and metamorphic rock formations. The old timers knew the significance of sphalerite as a potential gold indicator and called it “blackjack” or “rosin jack.”. Sphalerite comes in a range of colors, including grey or greyish

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

PYRITE FOR SALE. The mineral pyrite or iron pyrite is commonly referred to as Fool''s Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, pyrite was sometimes mistaken for gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2.

The star garnet from the Emerald Creek area in north Idaho is perhaps Idaho’s most famous gemstone. This locality is one of only two in the world that produce garnets with a star.

Pyrite is a pretty mineral (Fig. 1) common to Indiana, but it also has a dark side. It is composed of iron (Fe) and Sulfur (S) with a chemical formula of FeS2. Atoms are arranged in an isometric crystal structure (Fig. 2) that makes cubic crystals. It shows a brassy, bright metallic luster when fresh, but readily tarnishes to dull surfaces upon exposure (Fig. 3A).

This mining method exposes the coal contained in the overburden to water and air, and uncovers iron sulfide (pyrite), and when waste rock containing sulfides is exposed to air, an oxidization reaction occurs which releases sulfuric acids. The main sources of the product of sulfide oxidation are iron sulfide minerals (mainly pyrite and

Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Pyrite: At first glance, pyrite and chalcopyrite are similar in their color and shiny metallic luster. However, the two can be distinguished by their hardness. Chalcopyrite is a soft mineral that can be scratched by a nail, while pyrite is hard enough that a nail cannot dig into its surface.

Clusters of tourmaline can also be found with chalcopyrite and pyrite in crumbly oxidized rock. The second location is the famous Boulder Creek pyritohedron locality. Here, pseudo-dodecahedral pyrite crystals (pyritohedrons) are found within an alteration zone. The pyrite crystals are up to a centimeter across.

Pyrite or Iron Pyrite (FeS2) is a very common mineral that is present in many sedimentary rocks as framboidal crystals. Subject to certain conditions, pyrite is problematic in confined construction, such as under floor filling and bridge embankments. This is due to a chemical reaction that can cause pyritic backfill to swell.
