MOIL (earlier known as Manganese Ore (India) Limited) is a miniratna government manganese ore mining company headquartered in Nagpur, India. With a market share of 50%, it is the largest producer of manganese ore in India. [2] MOIL operates 11 mines in adjoining districts of Maharashtra and Madhya Pradesh.
Manganese is a chemical element with the symbol Mn and atomic number of 25. It is found as the free element in nature (often in combination with iron), and in many minerals. The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as
Manganese is another key mineral in Ghana. The country ranks as Africa's second-largest producer of manganese, with production reaching approximately 2.5 million metric tons in 2022. [38] In 2022, Ghana exported $436 million in manganese ore, making it the fourth largest exporter in the world.
Manganese ores are located in ore layers of 30-35 cm in the amount of 3-18 pieces and alternate with opoka (a type of carbonate-siliceous sedimentary rock [6]). Carbonate and oxidized layers are located in the upper part, and oxide ones in the lower part; in total, oxide ores – 26.5%, carbonate ores – 45.1%, oxidized – 15% and mixed ...

This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150 and 250 μm, increasing the surface area to aid leaching. The ore is then added to a leach tank of sulfuric acid and ferrous iron (Fe 2+) in a 1.6:1 ratio.
The lowest level of the ore zone is a 0.1 to 0.5 metres (3.9 in to 1 ft 7.7 in) layer of massive manganese oxides and hydroxides with some manganese carbonate (rhodochrosite). Above this is the main ore zone, a 3 to 9 metres (9.8 to 29.5 ft) layer of plates of similar minerals between bands of clay, silica and iron bearing material.
