Adoption of hot metal pre-desulfurization technology in steelmaking production
Introduction
The process of producing steel has changed since the introduction of the Bessemer converter in the 1850s. New technological advances have made it possible for steel to be produced quickly, with a high degree of precision, and with reduced environmental impact. The use of iron ores wi......
Electric furnace smelting of nickel sulfide ore
Nickel sulfide smelting furnace smelting
Nickel sulfide smelting furnace is mainly used for smelting of copper-nickel sulfide ore in China. The nickel sulfide smelting furnace adopts the principle of flash smelting, which can quickly extract the valuable metal and eliminate impurities. It can be ......
hydrogen sulfide
Hydrogen sulphide
Hydrogen sulphide (H2S) is a colorless, flammable, and poisonous gas that smells of rotten eggs. It is naturally released from decaying organic material, sewerage plants and hot springs. It is famously known as the sewer gas because of its sour, offensive smell that is produced ......
Composition and structure of natural gas
Natural Gas Composition and Structures
Natural gas is a mixture of compounds composed primarily of hydrogen and carbon, but sometimes included other heavier components such as nitrogen, sulfur, and oxygen. The lightest component of natural gas is methane, which has one carbon and four hydrogen at......
Sulfurite
Copper-bearing sulfur-silver ore, also called copper-bearing pyrite-silver ore, refers to a type of low-sulfur silver ore with disseminated copper minerals. Copper-bearing sulfur-silver ore contains a small amount of copper minerals, is an important silver and lead-zinc symbiotic mineralization sy......

Introduction to Molybdenum and Molybdenum Ore
Molybdenum is a chemical element with symbol Mo and atomic number 42. It is a silvery-white metal and a member of the 6th group of transition metals in the periodic table. It has a melting point of 4,607°F (2,539°C) and a boiling point of 7,465°F (......
High temperature superconducting materials
High-temperature superconducting materials
High-temperature superconducting materials, or HTSCs, refer to a new class of materials that exhibit zero electrical resistivity and dramatic enhancement of magnetic properties at temperatures higher than 30K, far above the previously known superconduct......
Recovery of molybdenum from molybdenum ores
Recovery of Molybdenum from Molybdenite
Molybdenite is a naturally occurring mineral composed of molybdenum sulphide. It is the primary ore used in the production of molybdenum metal and its compounds. The recovery of molybdenum from molybdenite involves several steps. This article describes the ......
Decomposition of tungsten concentrate
Wolframite
Wolframite is a rare mineral and an important source of the chemical element tungsten. Tungsten is used in many industrial and chemical applications, so wolframite is an important ore of tungsten. In addition to containing tungsten, wolframite is also a source of several other chemical......
