Slag
In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicatesof other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed. In many smelting processes, oxides are introdu
Iron Ore Mining Techniques Metal Extraction
Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale. The float ore area is dug up manually with picks, crow bars,

Iron mining Industrial History of Cumbria
The iron industry has slowly matured within the Lake Counties for centuries, with industrial growth spreading from the small bloomery and forge sites, coastal plateau workings and the narrow veins of the fells to the huge mining and iron smelting complexes of the late 19th and 20th centuries. The industry declined duriing the mid 20th century because of dwindling ore reserves, cheap

There is no overall historical account of iron mining in England, nor have any of its regions been covered comprehensively except perhaps Cleveland, Furness, and the Brendon Hills in West Somerset, and in all those areas the focus has been on modern mining (post 1750). Mining is touched upon in histories of the iron industry from Schubert(1957) onwards but the focus is

Different Types of Iron Ore 911metallurgist
05/10/2016 Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration. Iron formation is believed to be of
Michigan Iron Mines
Iron ore production in Michigan had a humble beginning. Prior to 1840, bog ore found in swamps was used in charcoal furnaces to produce pig iron. This iron ore was of low grade and deposits were small, thus limiting the size and advance of the industry. It was not until discovery of the iron formations in 1844, near the City of Negaunee that iron production in Michigan assumed any

Marginal mines closed. This process was helped by a down-turn in trade in the early to mid 1870s. Soon, a new generation of iron works was being built on Teesside. These used Bessemer convertors to turn the iron into steel, which was increasingly in demand. By 1883, therefore, production of Cleveland iron ore peaked at six and three-quarter
