Only one publiion on reduction of manganese ore by methanecontaining gas was found in literature. A Japanese patent4) described the production of manganese carbide by reducing pyrolusite (MnO 2) by methane–hydrogen gas in a fluidisedbed furnace at 250–520°C. At these temperatures, only manganese dioxide can be
1. Introduction. As a basic industrial material, manganese (Mn) and it compounds has extensive use in many aspects such as steel manufacturing, chemical metallurgy, battery materials, .Nearly 90 percent of Mn is used in steel production, where adding manganese can improve the toughness of the steel,,, .The manganese ores in nature are mainly rhodochrosite and pyrolusite, their main ...
Manganese is derived from pyrolusite ore, an impure manganese dioxide. In the procedure used to analyze a pyrolusite ore for its MnO2 content, a g sample is treated with g oxalic acid (H;C;O4•2 H¿O) in an acidic medium. Following this reaction, the excess oxalic acid is titrated with M KMNO, mL being required.
Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous, or columnar structure, sometimes forming reniform crusts.
Manganese recovery can be realized from lowgrade pyrolusite ore by roasting, using elemental sulphur at 350–500 °C or SO 2 at 500 °C followed by sulphuric acid or water leaching; also by hydrometallurgical treatment processes including aqueous SO 2 [15,22], FeSO 4, and biomass However, these methods do not meet the requirements for the simultaneous recovery of iron and manganese.
