IRON ORE

Corn Starch

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, or deep purple to rusty red. The iron is usually found in the form of magnetite (72.4% Fe),hematite (69.9% Fe), goethite (62.9% Fe), limonite 55% Fe or siderite (48.2% Fe).

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as “natural ore” or “direct shipping ore”, meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.

Glenmex source and ship iron ore from Australia, India, Brazil and South Africa.

MANGANESE ORE

Corn Starch

Manganese occurs as silvery grey in colour and is very hard and brittle in nature. It is always available in combination with iron, laterite and other minerals. Manganese in alloy form is an essential input in steel making and is one of the most important metals in an industrial economy. Manganese ores of major commercial importance are: (i) pyrolusite (MnO2, Mn about 63.2%); (ii) psilomelane (manganese oxide, containing water and varying amounts of oxides of Ba, K and Na as impurities; Mn commonly 45-60%); (iii) manganite (Mn2O3. H2O, Mn about 62.4%); and (iv) braunite (3Mn2O3, MnSiO3, Mn about 62% and SiO2 about 10%).

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal. Manganese ores from different sources vary widely in their contents of manganese, iron, silica, alumina, lime, magnesia, and phosphorous.

Glenmex offer various types of Manganese ore like Carbon ferromanganese (HC FeMn), Refined ferromanganese (RF FeMn) and Silica manganese (SiMn) alloys for Steel and Aluminium alloys industry.

BAUXITE

Corn Starch

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts.

Bauxite refineries produce alumina (aluminum oxide), which is used to create aluminum metal. Bauxite is also used to manufacture other industrial products, such as abrasives, cement and chemicals. Bauxite may be classified on basis of its predo minant alumina minerals into five types e. g. (1) pure gibbsitic bauxite (ii) Gibbsitic bauxite containing qua- rta (iii) Mixed gibbsitic-boehmitic bauxite (iv) Boehmi tic bauxite and (v) Diasporic bauxite.

Bauxite is found in most countries, but the larger deposits occur in the tropics. Major deposits of gravels mixed with sand were discovered in Australia and it became the world’s top producer of bauxite. Glenmex offer bauxite from Australia and other top producers include China, Indonesia, Brazil, and India and supply to aluminium and gallium industry.

GYPSUM

Corn Starch

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. Gypsum also crystallizes as translucent crystals of selenite

Crude gypsum is used as a fluxing agent, fertilizer, filler in paper and textiles, and retarder in portland cement. About three-fourths of the total production is calcined for use as plaster of paris and as building materials in plaster, Keene’s cement, board products, and tiles and blocks.

There are five basic forms of gypsum: selenite (transparent and some of the largest crystals found on earth), satin spar (fibrous and silky), alabaster (fine-grained, translucent white, used in ornamental works), rock gypsum (the most common form), and gypsite (soft, earthy, impure form) and can be defined in five types.

Glenmex source and supply bulk quantities of gypsum from Brazil, Turkey, and Madagascar.

CEMENT

Corn Starch

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet’s most-consumed resource.

Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as non-hydraulic or hydraulic respectively, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster).

Cement materials can be classified into two distinct categories: non-hydraulic cements and hydraulic cements according to their respective setting and hardening mechanisms. Hydraulic cement setting and hardening involves hydration reactions and therefore requires water, while non-hydraulic cements only react with a gas and can directly set under air.

We supply bulk quantities of cement of different grades like OPC 33, OPC 43 and OPC 53 by break bulk ships from India, Vietnam, Turkey, Egypt and Brazil.
