Übersetzung für "Eisengewinnung" in Englisch

The polymer would then function as a reductant and fuel, while the magnetite provides iron.

Certainly by Roman times, if not before, iron ore was being mined in the area of Ramsen and iron smelting in Eisenberg.

Apart from the modest level of iron extraction and processing, work in the forests and the operation of paper mills, the shoemaking industry in the region Pirmasens was the only real source of income.

The more the elaborate series of processing stages, subject to technological and economic laws of their own, has come between the ironworks and the farm, the more we have ceased to consider the close bond between them that formerly moulded the development both of ironmaking and of agricultural methods.

From recent research into the early history of ironmaking in different parts of the world, we know how closely the work of smelting the metal in tiny, primitive furnaces and then hammering it into usable shape was bound up with the methods of tillage then employed.

Also this method is suited only to recover iron from dustlike or fine-grained iron ores, but not when charging iron sponge particles having a substantial portion of particle sizes of above 3 mm.

By German Pat. No. 1086256 a method for recovering iron from dustlike or fine-grained iron ores has become known, with which a coke solid-bed is formed in a melting vessel by the addition of coke, in whose lower region a combustion medium, such as oxygen-enriched air, is injected immediately above the slag bath level.

Around 1840, a steel rolling mill was added and the latest iron ore extraction techniques were introduced.

What methods are therefore available to enable the works of the future to adapt iron-production techniques to this energy situation ?

The technology of iron production and processing in large scale was brought to Western Europe by the peoples of the Etruscans and the Celts returning from the Near East .

By the end of the 18th century, the factory had emerged as a local centre of iron production and processing.

Further, technically pure oxygen is fed to the blast furnace for obtaining iron and for producing a CO-rich synthesis gas that is drawn off as top gas.

Apart from the unavoidable impurities originating from iron production (for example residues of the additives customarily used there or oxygen and/or nitrogen in the case of carbonyl iron), the carbon-containing iron used in the process of the present invention preferably contains no further deliberately added constituents.

Particular preference is given to using a catalyst consisting of carbon-containing iron having a carbon content of at least 0.3% by weight and further comprising only unavoidable impurities originating from iron production but no deliberately added amounts of further constituents.

The history of Kloten is divided into three epochs: iron-producing in the 17th century, a lumber jack boom between the end of the 19th century and the beginning of the 20th century, and our current epoch, which is characterised by environmentally-friendly tourism

Ambrosio Ortega painted "Making the country". A representation of the Basque Society through the work and the sport. The author has chosen the most dangerous works as the fishing and the work of the iron.

It combines coal preheating and partial pyrolysis in a reactor, a melting cyclone for ore melting and a smelter vessel for final ore reduction and iron production.

Humans have left their mark in these wild forests throughout history: prehistoric stones with strange signs, ovens to reduce iron ore, limekilns, quarries to exploit ashlars or to make the magnificent fountain basins featured in the villages of the Lake Geneva Region.
