01-12-2020· Extraction of iron. There are a number of iron ores. However, it is uneconomical to extract iron from most of the ores. Two important ores used in extracting iron are hematite, Fe 2 O 3 and magnetite, Fe 3 O 4. First, these ores undergo several processes to remove the impurities.
Iron and aluminium. The method used to extract metals depends on the reactivity of the metal. Metals are used for a variety of purposes. An alloy is a mixture of a metal and another element.
Removal of most gangue and collection of some byproduct minerals (e.g., Mo, Ni, Pb, Zn) to avoid further expense in materials handling, transportation, and smelting Heat-induced separation of complex sulfides into copper sulfides, iron sulfides, and sulfur; removal of sulfur as off gas (SO2) and removal of gangue via slag; in oxygen-
The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows into the clay-filled iron notch at the base of ...
