Manganese is considered a relatively rare metal as concentrations of it in ore of commercial importance are geographically limited. In nature, manganese is found in the form of oxides, carbonates, and silicates. Manganese ores are complex in the sense that they not only consist of a complex oxide mineral assemblage but these minerals are …

Over the years, mining and metallurgical activities have rapidly influenced the human population. The manufacturing process of manganese (Mn) compounds and their use in industries increased the negative effect on the environment. Therefore, the recovery process of Mn from metal-containing wastes has become very crucial.

Manganese is an ancient metal that was discovered as a distinct element in 1774. This year marks the 250th anniversary of its discovery. Yet despite its storied history, most miners in the space agree the magnitude of manganese's importance and its multifaceted applications have long been overlooked. Evidence indicates the first known …

Although mine drainage is usually thought of as acidic, there are many cases where the water is of neutral pH, but still contains metal species that can be harmful to human or aquatic animal health, such as manganese (Mn) and zinc (Zn). Typical treatment of mine drainage waters involves pH adjustment, but this often results in excessive sludge …

This process is especially suitable for handling the Fe-Mn ores with a high proportion of Fe-Mn composite oxides (as shown in Fig. 2). The process can provide an alternative and effective method to synchronously recover Fe and Mn elements from the Fe-Mn ores, and can produce high added value final magnetic products (manganese ferrites).
