The new technique makes it possible to extract phosphorus from manganese ore, which is of particular interest in industry.
The essence of the technology is the heat treatment of manganese concentrate using carbon monoxide (CO) at a temperature of approximately 1600-1630 degrees Celsius. This method demonstrates the simplicity and economic feasibility of reducing phosphorus levels in manganese ore, the press service added.
Manganese is an important component in the production of various types of steel, including structural, corrosion-resistant, heat-resistant and other specialty steels. Ferroalloys containing manganese are often used to improve the properties of steel.
The press service added that manganese ore mined in Russia contains phosphorus, which, when melted together with manganese, deteriorates the quality of the steel produced. Research by MISIS scientists has shown that blowing manganese-containing melts with carbon monoxide can reduce phosphorus levels in melts by 20-40%.
