The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common form of sulfide minerals.. 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

Pyrite 4mm Diamond Cut Faceted Round AA Grade 15

Pyrite, an iron sulfide, is characterized by its metallic luster and brass-yellow hue that have earned it the nickname "fool's gold." Pyrite is actually lighter in color than gold as well as harder and more brittle. It derives its real name from the Greek "pyrites," meaning "of fire," as it creates sparks when struck on steel.

Recovery of Platinum, Palladium, and Gold From Stillwater

By E. G. Bdglin, 1 J. M. Gomes, 2 T. G. Carnahan,2and J. M. Snider3 ABSTRACT The Bureau of Mines devised a procedure for selectively extracting platinum-group metals (PGM) and gold from Stillwater Complex flotation concentrate. The Stillwater Complex is the only major U.S. PGM re source.

The Gutaishan deposit is a slate-hosted lode Au–Sb deposit in the Xiangzhong Sb–Au metallogenic province, South China. The deposit has a proven reserve of ca. 9 -t gold at an average grade of 13-g/t and contains 2500-t Sb. The deposit represents the product of a complex ore-forming process, comprising four different stages, of which the third stage is the main gold–stibnite bearing stage.

Pyrite: The mineral pyrite information and pictures

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.

Gold Smelting Refining Process

Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silver-gold concentrates can be smelted too. Under this consideration, a concentrate must contain at least 20 oz/t of gold. Obviously, if the higher grades are better and 50 oz/t is a good average value.


Provided is a method for leaching gold from gold ore containing pyrite. Said method for leaching gold includes a pretreatment step that includes a step (1) in which gold ore containing pyrite is prepared, and a step (2) in which the gold ore is heated to 450C or higher, and the pyrite in the gold ore is thermally decomposed into iron(II) sulfide and elemental sulfur.
