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 UNROASTED IRON PYRITES Pyrite is an iron sulfide mineral and one of the most ubiquitous minerals of earth's crust. It is found in igneous, metamorphic and sedimentary rocks and crystallizes at both high and low temperatures. Its yellow color and metallic luster occasionally fool inexperienced people who confuse it with gold - hence the name "fools gold". The uses of pyrite are declining. The main uses today are the production of sulfur dioxide for the paper industry and sulfuric acid for the chemical industry. Other sources of these substances are replacing what was once produced from pyrite. It is rarely mined for its iron content because the associated sulfur contaminates the iron to render it brittle and useless for most applications.
