Feldspar Feldspar Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldsparrich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.
Iron is a chemical element and a is the second most common metal on Earth, and the most widelyused makes up much of the Earth's core, and is the fourth most common element in the Earth's crust.. The metal is used a lot because it is strong and cheap. Iron is the main ingredient used to make iron is magnetic (attracted to magnets), and its compound magnetite is ...
Most of the rubber is consumed by the tyre industry which is almost 52% of the total production of India. Kerala is the leading consumer of rubber, followed by Punjab and Maharashtra. Though, India is one of the leading producers of rubberit still imports rubber from other countries.
Mica is birefringent and is therefore commonly used to make quarter and half wave plates. Specialized applications for sheet mica are found in aerospace components in air, ground, and sealaunched missile systems, laser devices, medical electronics and radar systems.
Mar 14, 2014· 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). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to .
Jul 30, 2016· A pioneering steel alloy matrix developed in India, Wootz steel is a crucible steel characterized by a pattern of bands that was known in the ancient world by many different names such as Ukku, Hindwani and Seric Iron. This steel was used to make the famed Damascus swords of yore that could cleave a freefalling silk scarf or a block of wood with the same ease.
More than 90% of SA's iron ore is magnetite. The world's production of iron ore for 2012 was dominated by Australia with 27% or 520 Mt, followed by Brazil with .
It is most commonly black, but can be blue, red, orange, yellow or swirled. Obsidian is relatively soft and breaks or chips easily upon impact so it is not appropriate for jewelry such as rings and bracelets but it is used in earrings, brooches and pendants .
Generally most magnetite banded iron formation deposits must be ground to between 32 and 45 micrometers in order to provide a lowsilica magnetite concentrate. Magnetite concentrate grades are generally in excess of 63% Fe by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price.
The highest level of silica content in it makes it the most preferred mineral to be used in various industries and also for other personal uses. It is invariably used for fillers, extenders along with providing smoother uniformity, improving workability and prevents cracking.
Deaerators are used to heat feedwater and reduce oxygen and other dissolved gases to acceptable levels. Corrosion fatigue at or near welds is a major problem in deaerators. Most corrosion fatigue cracking has been reported to be the result of mechanical factors, such as manufacturing procedures, poor welds, and lack of stressrelieved welds.
Indian rubber industry has been growing in along with the strength and importance, as a part of India's burgeoning role in the global economy. India is the world's largest producer and the third largest consumer of natural rubber and is also one of the fastest growing economies globally.
The total in situ reserves of iron ore in the country are about 1,23,17,275 thousand tonnes of haematite and 53,95,214 thousand tonnes of magnetite. The resources of very highgrade ore are limited and are restricted mainly in the Bailadila sector of Chhattisgarh and to a lesser extent in BellaryHospet area of Karnataka and Barajamda sector in Jharkhand and Orissa.
Magnetite is widely used in most densemedium processes in the coal industry because of its higher specific gravity, stability in suspension, lower viscosity, and easy availability, recovery and reuse. To keep the suspension at the desired specific gravity and low viscosity, it is necessary to extract continuously some of the contaminating slimes from the medium.

Calcite is a mineral used in many ways, serving as a construction material and aggregate, a pigment, agricultural soil additive and an ingredient in pharmaceutical products. Calcite is most often found in limestone and marble, with many applications in those forms. Keep Learning.
Iron ore is the main ingredient in steel, which makes up 95 percent of the metals used in the world per year. Two billion metric tons of raw iron ore are produced in a year. The world's largest single producer of iron ore is Brazilian mining company Vale, which produces over 350 million tons of iron ore annually.
