1 Introduction Manganese is an essential alloying element in the steel making process [ 1 ]. Many of the properties of the steel are achieved by appropriate addition of manganese ferroalloys. Basic manganese ferroalloys, viz. Ferromanganese (FeMn) and silicomanganese (SiMn), represent about 42% of the total ferroalloy production in India [ 2 ].

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of ...

The reduction of higher manganese oxides to MnO in the prereduction zone of a ferromanganese furnace is largely decisive for the overall energy efficiency and climate gas emissions for the overall production process. Kinetics of the gassolid reaction between the ore and CO(g) in the ascending furnace gas is dependent on the ore characteristics. The aim of this study was to elucidate the ...

Silicomanganese (SiMn) is a metallic ferro alloy which is being used to add both silicon (Si) and manganese (Mn) as ladle addition during steelmaking. Because of its lower carbon (C) content, it is a preferred ladle addition material during making of low carbon steels. SiMn is a ferroalloy composed principally of Mn, Si, and Fe (iron), and ...
