MINERALS OF COMPANY


IRON ORES AND CONCENTRATES
Mineral Detail:

MINERALS IRON ORES AND CONCENTRATES Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). MAGNETITE Magnetite is best known for its property that it is strongly attracted to magnets. Some forms of Magnetite from specific localities are in fact themselves magnets. This form is known as Lodestone, and is the only mineral that acts as a natural magnet. Although its magnetism is weak, it is strong enough to attract large nails. Due to its magnetic properties, small iron particles are often found clinging to its surfaces. Some dealers intentionally place metallic filings on a Lodestone to demonstrate its magnetism. HEMATITE Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals such as Garnet, Spinel, and to some extent, Ruby. Non-crystalline forms of Hematite may be transformations of the mineral Limonite that lost water, possibly due to heat.


PUMICE STONE
Mineral Name:
Mineral Detail:

MINERALS PUMICE STONE Pumice is a light and porous type of pyroclastic igneous rock. It is formed from the lava that is full of gas. During the explosive volcanic eruptions, the liquid lava is ejected in the air. As the lava hurtles through the air, it cools and the gases escape from the rock, leaving it full of holes. Any type of igneous rock can form pumice rock, provide suitable eruptive conditions it get. It can be andesite, basalt, dacite or rhyolite. When larger amounts of gas are present in the rock, the resultant is a finger-grained variety of pumice, which is known as pumicite. Pumice is popular in making lightweight concrete and is used as abrasive, particularly in polishes and cosmetics exfoliants. When pumice is used as an additive for cement, its fine-grained version knowns as pozzolan is mixed with lime to form a light-weight, smooth, plaster-like concrete. This type of concrete has been in use since Roman times.


MINERAL OILS
Mineral Name:
Mineral Detail:

MINERALS MINERAL OILS Fossil fuel or mineral fuel, hydrocarbon and natural energy source containing high levels of carbon. Coal, oil and natural gas; is a prime example of such fuels. It is formed by the dissolution of dead living organisms in an oxygen-free environment for millions of years.


DOLOMITE
Mineral Name:
Mineral Detail:

MINERALS DOLOMITE is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.


MANGANESE ORES AND CONCENTRATES
Mineral Detail:

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.
