Pyrite

Feature of Pyrite Stone

Copper pyrite because its yellow color and bright metallic luster, and is often mistaken for gold, so it is also referred to as the “fools gold”. The ingredients usually containing cobalt, nickel, and selenium, type with NaCl crystal structure. Composition and belong to the same orthogonal (orthorhombic) crystal system called white iron ore. Component is often present in trace amounts of cobalt, nickel, copper, gold, selenium and other elements, content is higher in the process of the sulfur can be extracted in the comprehensive recovery and utilization.

Distribution of Pyrite

The world famous origin with Spain, the Czech republic, Slovakia, the United States and China, China pyrite of proven reserves in the world. Pyrite is the most widely distributed in the crust of sulfide. A tiny disseminated in magmatic rocks, pyrite, as the product of magmatic hydrothermalism after. Often contact metasomatic deposit, pyrite and other sulfides symbiosis, formed in the hydrothermal process in the late stage. In hydrothermal deposit, pyrite and other sulfides, oxide, quartz and other symbiotic; Sometimes pyrite formed huge accumulation. In sedimentary rock, coal measures and sedimentary deposit, pyrite show mass, tuberculosis, or lens output. In metamorphic rock, pyrite is often metamorphism of new product.

Application of Pyrite

The main raw material of pyrite is the production of sulphur and sulphuric acid. Can be extracted with Au, Co, Ni is associated elements. Medicinal natural copper pyrite (smash or calcined), alias stone pulp lead. Efficacy: scattered stasis pain, bone healing. Medicine preparations, invigorate the circulation of the pain, the army fall break. System of middle school chemistry: the application of sulfate sulfur or first pyrite in air combustion or roasting, for sulfur dioxide gas. Sulfur dioxide oxidation into sulphur trioxide is the key to the production of sulfuric acid, this reaction at room temperature and catalyst does not exist, in fact not be performed.
