the manganese ore-modied electrodes with properties of classical carbon felt electrodes modied with magnetic ferroferric oxide. We also studied the removal of the chemical oxygen demand and the enrichment in ammonia nitrogen. Results show that the maximum voltage of the manganese ore-modied carbon felt electrode is 1.7 times higher than that of ...
Manganese is, an important industrial mineral used in the manufacture of various products, including in the refinement of iron ore and as an alloy in steel. China has rich resources of manganese (Mn), with the majority of deposits located in southern China. The common types of Mn deposits are sedimentary, hydrothermally modified, and …
Manganese is an essential trace element that is naturally present in many foods and available as a dietary supplement. Manganese is a cofactor for many enzymes, including manganese superoxide dismutase, arginase, and pyruvate carboxylase [ 1, 2 ]. Through the action of these enzymes, manganese is involved in amino acid, cholesterol, glucose ...

High carbon ferromanganese (HCFeMn) is an alloy composed primarily of manganese (around 70-80%), carbon (6-8%), and silicon (1-2%). It is a type of ferroalloy, which is an alloy of iron and one or more other elements, used in the production of steel and other alloys. The primary use of high carbon ferromanganese is in the production of steel.
