The closest industrial process to the electrolytic copper extraction they hope to see is aluminum production by an electrolytic process known as Hall-Héroult process, which produces a pool of molten aluminum metal that can be continuously tapped. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. Each of these oxides is heated with carbon to obtain the metal. The process containing the extraction or refining of metals is known as metallurgy. Smelting uses heat to separate the valuable metal from the rest of the ore. Hydrometallurgy, sometimes called leaching, involves the selective dissolution of metals from their ores. The carbon gains oxygen, and is therefore oxidised. BloodOre. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore. This is called extracting the metal. Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production.

Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. Spell. Therefore, metals are generally extracted by subjecting their ores to reduction by chemical methods or by electrolytic methods. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The metal is recovered by electrolysis of the solution. Intermediate Extraction. DylanFletcher01. The metal oxide loses oxygen, and is therefore reduced. These are called gangue or matrix. Here we will consider the raw metal known as PigIron. Answer. The leaching process uses an aqueous solution to extract metal from the ore. A concentration of minerals is only called an ore deposit if it is profitable to mine. Match. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements. Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied.
