Pyrites, also known as pyrite, pyrrhotite and ilmenite, have a molecular formula of FeS2 and a molecular weight of 120. Pyrite is an important chemical mineral raw material, which is mainly used to produce sulfuric acid.
Properties: the most common crystals of pyrite are hexahedron, octahedron and pentagonal dodecahedron. There are fine stripes on the surface of hexagonal crystal. Sometimes many crystals combine to form various polycrystals. Sometimes it is golden yellow, sometimes it is brass, and has a bright yellow metallic luster. The specific gravity is 4.95-5.20. The hardness is 6.0-6.5. The streaks are green and black. It is brittle and easy to be broken when it is knocked. The broken surface is uneven. Source: pyrite deposits are mainly formed by endogenesis. In addition, the pyrite deposit formed by coal sulfur deposition is also worthy of utilization. There is a large amount of sulfur in the UN solidified magma in the depth of the earth. When the magma intrudes into the crust, the sulfur contained in the magma is separated due to the decrease of pressure. These sulfides combine with various metals to form different sulfides and minerals. When the magma contains a lot of sulfur and oxygen, it will produce pyrite; otherwise, it will produce pyrrhotite. packed in bulk. purpose: pyrite is an important chemical mineral raw material, mainly used for manufacturing sulfuric acid. Some of them are used as chemical raw materials to produce sulfur and various sulfur compounds. It is widely used in rubber, paper, textile, food, match industry and agriculture. Especially in the national defense industry, it is used to manufacture various explosives and smoke agents. Pyrite is used as raw material to produce sulfuric acid, and its slag can be used for ironmaking and steelmaking. If the sulfur content of slag is high and the iron content is not high, it can be used as the auxiliary raw material of cement mixture. In addition, pyrite is often associated with copper, lead, zinc, molybdenum and other sulfide deposits, and contains gold, cobalt, molybdenum and rare element selenium, which can be comprehensively recycled. storage and transportation conditions can be carried by railway, road or ship. Pyrite should not be stored in the open air or in the warehouse with poor ventilation. Mine delivery.
