Manganese in natural manganese ores mostly exists in the form of oxides, carbonates, and silicates. Manganese minerals with industrial value mainly include pyrolusite (MnO 2), psilomelane (mMnO·MnO 2 ·nH 2 O), manganite (Mn 2 O 3 ·H 2 O), braunite (Mn 2 O 3), and hausmannite (Mn 3 O 4), as well as rhodochrosite (MnCO 3) …
The beginning of the Manganese ore processing involves a multistage crushing workflow. From there, the production of ferromanganese, the manganese ore is mixed with iron ore and carbon and then reduced either in a blast furnace or in an electric arc furnace. The resulting ferromanganese has a Manganese content of 30% to 80%.

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.
Most underground mining of the manganese is generally done by room and pillar method. Mining at Nchwaning and Gloria mines uses two shafts when it was initiated in 1981, one vertical hoisting shaft that is 450m deep and another vertical shaft. Now further rooms and pillar rooms are made with low grade ore for easier mining.

Workers at manganese mining and processing facilities have the greatest potential to inhale manganese-rich dust. Without proper protective equipment, these workers may develop a permanent neurological disorder known as manganism. Each manganese mine is unique and presents its own suite of potential hazards and preventative measures.
A questionnaire was developed and sent to manganese mining and processing facilities across the world in order to obtain information on manganese uses and emissions. The questionnaire was designed to be applicable to different types of manganese uses, but also to be site-specific. The questionnaire covered site …

The manganese mining process that used to deal with manganese oxide ores usually need to crush the ores into 0-6mm to 0-10mm, and then classify them. The coarse minerals are sent to jigging separation, and the fine minerals are sent to shaking table separation. 3. Strong magnetic separation process
The largest single manganese mine in the world is the Nsuta mine on the Gold Coast of Africa with -a modern open pit of SOlne 3,000 tons per day capacity. rhe largest single deposit known is the Chiatura in the Caucasus Mountains. All geographical entities, however, have possibilities for in creasing reserves by further exploration and discovery.
