Manganese - Simple English Wikipedia, the free encyclopedia
Manganese is chemical element 25 on the periodic table. Its symbol is Mn. (Some people get it confused with magnesium, the symbol is Mg). Manganese is used a lot in steel to make it stronger. This is the main use for manganese metal.
Manganese processing | Britannica
It can be produced by two methods. In the first, ores are selected on the basis of their acidity so that, on smelting, 70 to 80 percent of the manganese is recovered in the melt while a slag containing 30 to 42 percent manganese is also obtained. (This slag can be resmelted to produce silicomanganese; see below.) The second method, which employs basic ores or fluxes, recovers 85 to 90 percent of the metal and generates a slag low enough in manganese to be discarded.
Manganese (Mn) has an atomic number of twenty-five, and has twenty-five protons in the nucleus of an atom. It exists as a naturally occurring free element Interesting Manganese Facts: Johann Gottlieb Gahn was the first scientist to isolate manganese from pyrolusite in 1774. Pyrolusite, as it was called...
Method for producing cement using manganese slag as raw
A method for producing cement is disclosed. The method has the advantages that a setting time can be shortened as compared with conventional cement, and a manganese slag can be treated at low cost without giving load to environment, by using the manganese slag which has conventionally been subjected to waste disposal, as a cement raw material.
10 Different Types of Casting Process | MachineMfg
Steel, iron and most nonferrous alloy castings can be obtained by sand casting. The casting has high density, few defects such as pores and slag inclusion, and high mechanical properties. Such as gray cast iron engine box, high manganese steel elbow and so on.

Effects of Al Addition on the Reaction between High
2020/06/13 · Herein, the effect of Al addition on steel and slag compositions as well as inclusions of high‐manganese steel is investigated by slag–steel reaction. The results show that Al content in steel decreases, Si increases greatly, and Mn increases a little after Al addition.
Leaching Characteristics of Iron and Manganese from Steel
2019/07/02 · Steel slag reuse as a construction material is an attractive solution for the management of the industrial byproduct.

Advantages and risks of using steel slag in preparing
Abstract. It had been reported that iron and manganese oxides in steel slag enhanced the production of humic acid (HA) from low-molecular-weight compounds, such as phenolic acids, amino acids, and saccharides. In the present study, this function of steel slag was applied to the composting of raw organic wastes (ROWs).
