Deep Sea Mining an overview ScienceDirect Topics
Deep-sea mining is an emergent industry targeting three main resources of interest: manganese nodules, seafloor massive sulfides and cobalt crusts. Interest in deep-sea minerals exists within the national jurisdictions of coastal States and in Areas Beyond National Jurisdiction (ABNJ). Within ABNJ, the International Seabed Authority (ISA) isDue to immense scientific importance and industrial applications of Mn, recovery of manganese by different methods like solvent extraction, precipitation, bioleaching, chemical and biological oxidation, etc. has numerous technical applications and significant in utilizing the elevated mining effluents (Fig. 1).Solvent extraction and A review of biotechnology processes applied for manganese

Manganese-contaminated groundwater treatment by novel
Manganese is an abundant transition metal that disperses readily through soil and water. It can exist in many oxidation states (from Mn 3− to Mn 7+).In aquatic environments, the main forms areMining of the manganese project. The project is proposed to be developed as a small-scale open-pit mining operation, using a conventional truck-and-shovel mining method. Ore will be mined at a strip ratio of 5:1. The mining operations will target the orebody in a three-zone cutback sequence, starting with the upper section of the K Hill Battery Manganese Project, Botswana Mining

In 2019,An activated carbon filter removes excess chlorine, as well as small quantities of iron/manganese particles. Chlorine oxidizes iron best at a pH of 6.5–7.5. Chlorine should not be used for high levels of manganese, because manganese requires a pH higher than 9.5 for complete oxidation.

The excessive use of manganese containing products, mine waters, steel manufacturing industries lead to environmental pollution. Although it is essential for human life, at levels exceeding 0.1 mg/L, manganese in water supplies causes an undesirable taste in beverages and stains sanitary ware and laundry. The presence of manganese(II) inThis study assessed the significance and potential impact of potentially toxic element (PTE) (i.e., Mn, Pb, Cu, Zn, Cr, Cd, and Ni) pollution in the surface soil from an abandoned manganese mining area in Xiangtan City, Hunan Province, China, on the health of residents.

A global life cycle assessment of manganese mining processes
Manganese can be mined using underground mining or surface mining methods depending on the ore deposit and the fineness of the ore (Zywicka, 2004). The inferior grade of ores in mines may undergo the beneficiation process due to increasing demand in the national and international market to upgrade the quality of the mined ore.Chemical precipitation is a very efficient and widely used method for heavy metals from various wastewaters. This technique involves conversion of soluble manganous ion to an insoluble precipitate and to achieve significant manganese reduction by precipitation, a reaction pH above 9.4 is required [23]. 2.1.1.A review of technologies for manganese removal from wastewaters
