1. Introduction Manganese (Mn) is an element that can occur in nature as oxides, hydroxides, silicates and carbonates, being found in various types of mineral classes [1,2]. Generally, Mn occurs in small proportions in soils as secondary minerals, originated during water/rock–soil interaction [3]. The Mn ore is one of the most essential raw materials for producing metallic alloys, especially combined with iron (Fe) for steel manufacturing.
