Powdered coke (coke): Coke powder is obtained from the distillation of coal by pressurized air isolation.

Coke powder is mainly used for copper, lead, zinc, titanium, antimony, mercury and other nonferrous metals smelting blast furnace, from the reducing agent, heating agent and material column skeleton role. Blast furnace using coke instead of charcoal, laid the foundation for modern large-scale blast furnace. For the blast furnace operation to achieve better technical and economic indicators, smelting with coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal nature. In addition to a large number of coke for iron and nonferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferro-alloys, their quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification of coke, strict requirements for strength, but requires good response, high ash melting point; calcium carbide, coke production requirements
