Mining sector is one of the core sectors of economy. It provides basic raw materials to many important industries. Mining sector (including fuel, atomic, major and minor minerals) contributed about 2.4% of GDP in 2014-15 as per the data released by Central Statistical Organization under Ministry of Statistics & Programme implementation.
Daniel Thomas "Danny" Rand is the only child of the billionaire owners of Rand Enterprises. He lost his parents in a plane crash which resulted in the young Rand being rescued by monks and taken to K'un-Lun where he trained and eventually took the title of the Iron Fist.
Iron processing: Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting.
Production. Cast iron is made from pig iron, which is the product of smelting iron ore in a blast furnace.Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.

CAB Incorporated is a product supplier & distributor of cast irons: gray iron, ductile iron and malleable iron castings.
Types of surface mining . Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surface.Coal and Lignite are the two principle minerals that are extracted through this method.
Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites.
Evolution of Blast Furnace Iron Making. The origin of the first smelting of iron is concealed in the unrecorded history of human civilization. The first evidence of iron implements being used in ancient times actually comes from Egypt where an iron tool was found in a joint between two stones in a pyramid.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back ...
In Australia, all magnesite deposits are mined by open-cut methods. During mining the strip ratio, that is, the quantity of magnesite ore to waste material, may be high.
Ironsand also known as iron-sand and iron sand is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.
As with most iron ore mines throughout the world, all the major Australian iron ore mines are open cut. The ores from the major mines in Western Australia's Pilbara region are hauled from working faces to crushing and screening plants using trucks that can carry over 300 tonnes.
There are several methods by which a limited supply of hot metal could be stretched by increasing scrap utilization. Process optimization of current oxygen steelmaking technologies will result in small improvements in yield by reducing both the iron content and total volume of slag produced.
Mike Fitzpatrick explains how first cast iron and then steel were developed, and the vital part these discoveries played in the industrial revolution.
