Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a . The ores used in ancient smelting processes were rarely pure metal compounds. Impurities were removed from the ore through the process of slagging. Slag is the material in which the impurities from ores (known as gangue), as well as furnace lining and charcoal ash, collect.

Finally, we break up the burnt iron ore into cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3). Step 3. Building furnaces.

Ottawa, Government bureau, At the present time there are two main types of electric furnace for smelting iron ores: (1) The Elektrometall furnace, in which the ore is pre- heated and partially reduced in a shaft before it reaches the smelting chamber; the heating of the ore in the shaft and the chemical reduction of the iron in the ore being materially as- sisted by the circulation of the furnace gases, which is character- istic of this furnace.

THE rapid growth of the application of the electric furnace to the metallurgy of iron and steel is certainly the most noteworthy feature of the development of this industry during the last : H. Carpenter. the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter.
Lead concentrations can be %, and the sulfur content of sulfidic ores is in the range of %. Zinc concentration is in the range of %, with sulfur content in sulfidic ores in the range of %. Refining: Steelmaking. The refining of iron to make steel is where the carbon content of hot metal is lowered, usually to less than 1 % by an oxidation process in a steelmaking furnace.
At the same ime, alloying t materials are added to the furnace to achieve the required chemical composition of File Size: KB.

Essentials ofPrehistoric Iron Smelting The production ofiron from an ore seems to bea simple reduction process: the iron oxide of the ore (Fe) is reduced to elemental iron by the carbon monoxide (CO)produced by the burning ofcharcoal (Fe+3CO~2Fe+3CO2). However, there are several difficulties inthis process: one isthe tendency ofthe.

Harcourt () Elementary lathe practice by T. Palmateer (). Iron ore routes. There were two main routes by which iron ore was shipped to Germany from Sweden. The Eastern Route. Annually from May to November, ore from the Northern region was shipped from the port of Luleå down the Gulf of Bothnia to the German north Baltic ports at Lübeck.
Iron Ore: Mineralogy, Processing and Environmental Issues. summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (e.g., production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.
The largest furnace that Electric Smelters has built is smelting tons of iron ore in Norway (per day, presumably). This was erected in but is not mentioned in Millers report of cited later. The smallest furnace has a capacity of pounds in hours and is employed for reducing precipitates.
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature.
The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being. With respect to iron ore imports and exports, China imported about 65% of the world's seaborne iron ore trade infollowed by Japan (11%), Europe (10%), and Korea (6%), which is a clear indication that the Asian countries are driving the international iron ore industry.
Zinc smelting. Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.

Smelting involves heating up iron ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Perhaps tons of iron could have been obtained over the years.Swedish iron ore is very pure (specifically low sulphur content). Before the modern Linz-Donawitz-steelmaking process, sulphur impurities were very costly to remove.
However the main reason Germany desired Swedish steel was not for its quality but its quantity. 40% of Germanys prewar iron ore supplies was imported from Sweden.
