MINERALS MANGANESE ORES AND CONCENTRATES Steel becomes harder when it is alloyed with manganese. It has similar applications when alloyed with aluminum and copper. Hardened steel is important in the manufacture of construction materials like I-beams (24% of manganese consumption), machinery (14% of manganese consumption), and transportation (13% of manganese consumption).Manganese dioxide is used to: manufacture ferroalloys; manufacture dry cell batteries (it's a depolarizer); to "decolorize" glass; to prepare some chemicals, like oxygen and chlorine; and to dry black paints. Manganese sulfate (MnSO4) is used as a chemical intermediate and as a micronutrient in animal feeds and plant fertilizers. Manganese metal is used as a brick and ceramic colorant, in copper and aluminum alloys, and as a chemical oxidizer and catalyst. Potassium permanganate (KMnO4) is used as a bactericide and algaecide in water and wastewater treatment, and as an oxidant in organic chemical synthesis.

MINERALS MAGNESITE Magnesite is a compound of magnesium, its chemical formula is MgC03, and its color varies between white, yellow, grey and brown. It is found in nature as cryptocrystalline and crystalline. It is a tough and complex mineral, and is an alteration product of serpentinite or similar rock types. There are magnesite reserves in Konya, Balıkesir, Bursa, Bilecik, Ankara, Kütahya, Eskişehir and Erzincan.
