Uses and Toxicity of Pyrite (Fool's Gold) – A Comprehensive Guide

Pyrite, commonly known as fool's gold, is a common sulfide mineral with the chemical formula FeS₂. Its metallic luster and golden color often mislead people into thinking it’s gold. However, pyrite has various important uses in industry — from metallurgy and battery research to construction and decorative applications. While generally stable, proper handling is advised due to potential sulfur dioxide release under high heat or oxidation.
