How To Spot Pyrite (Real or Fake) Identification Guide

To identify pyrite, also known as fool's gold, look for its metallic luster and brass-yellow hue, often with a greenish or blackish streak. Pyrite typically forms in cubic or pyritohedral shapes, distinguishing it from gold's soft, malleable texture. It's harder than gold, ranking about 6-6.5 on the Mohs scale.

Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation

Ore A contained approximately 61 pct arsenopyrite and 9 pct pyrite, and ore B contained 35 pct arsenopyrite and 24 pct pyrite. The low-grade ore contained only 1 pct arsenopyrite and 5 pct pyrite. Scanning electron microscopy analysis and X-ray diffraction patterns of the ores indicated that virtually all of the arsenic was present as arsenopyrite.

Pyrite

Pyrite is a hard mineral (Mohs hardness over 6) but gold is soft. It is easy to scratch pure gold with a knife or needle. You can not do it with pyrite. Its crystals are brittle but gold is malleable. Also the color is different. Gold is bright golden yellow, but pyrite is somewhat paler or even greenish yellow. In powdered form is greenish black.
