Get Price2006. 6. 27. · Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state.
Get PriceThe method used to extract metalsfrom the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metalsuch as iron may be extracted by reduction with carbon or carbon monoxide.

Get Priceextracting metals from their ores: reduction with carbon electrolysis (using electricity). The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Most metals are found combined with other elements, as compounds in ores. These metals must be extracted from their ores before they can be made useful.
Get Pricemetals are extracted from their ores according to their reactivity series. firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.
Get PriceAn ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Most metals are extracted from ores found in the Earth's crust. Ores are often metal
Get Price4.7 Explain why the method used to extract a metal from its ore is related to its position in the reactivity series and the cost of the extraction process
Get PriceMining with microbes: Extracting metals from low-grade ores is usually a tricky business, but some bacteria have no problems with it. The metal industry is using these tiny helpers to make their
Get PriceReduction of Metals (Extraction from Ore) There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal.
Get PriceExtraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as
Get PriceMetallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.
Get Price1. During the extraction of platinum group metals ,as these metals are rare, a lot of nickel and copper are produced. 2. The platinum group metals are extracted during the refining process. 3. The platinum ore will be extracted from the ground and into a refinery or processing plant.
Get Price16.2 GENERAL PRINCIPLES OF EXTRACTION OF METALS The process of extracting the metals from their ores and refining them is called metallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.
Get PriceExtracting metals from their ores. notes on extraction of metals metallurgy grade 11 . the process of extracting a metal in pure form from its ore is known as metallurgy. the process of treatment depends on upon the nature of the ore, impurities, and the metal. from the extraction point of view, the metals can be broadly classified into five.
Get PriceThe reduction method depends on the reactivity of the metal. For example, aluminium and other reactive metals are extracted by electrolysis, while iron and other less reactive metals may be extracted by reaction with carbon or carbon monoxide. 1.2K views · Answer requested by
Get PriceThis page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis. Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section.
Get Priceand machines for extracting metal from the ore focused on "eliquation" of metals. historically focused on the processing of iron-rich monometallic ores. At the same time, involving the poor (siderite) and complex (particularly titanium) magnetite ores in processing.
Get PriceHydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials.
Get PriceThe way we extract a metal from its ore depends on the position of the metal in the reactivity series. Carbon is used to reduce oxides of metals below it in the reactivity series. Metals above carbon in the reactivity series cannot be extracted from their oxides by heating with carbon.
