Ores are often metal oxides, although sulfide and carbonate ores are also common. Extraction methods The extraction method used depends upon the metal's position in the reactivity series .
The method used to extract metals from 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 metal such as iron may be extracted by reduction with carbon or carbon monoxide.
The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
This 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.
An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.
Extracting metals from their ores. STUDY. PLAY. List some factors that contribute to the price of a metal. The abundance of the ore in the Earth's crust. The mining costs. The energy costs in the process of extracting the metal from its ore. The demand for the metal. Why should metals be recycled? 1.
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct
Saving of raw materials and energy by not having to first extract the iron from the ore. Avoiding the pollution problems in the extraction of iron from the ore. Not having to find space to dump the unwanted iron if it wasn't recycled.
Metals are very useful. Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. The method used to extract a given metal from its ore depends upon the reactivity of the metal and so how stable the ore is.
Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.
The method used to extract a given metal from its ore depends upon the reactivity of the metal and so how stable the ore is. Each metal requires a different extraction technique and purification etc.
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 categories.
It simply means purifying the metal according to reactivity series.CARBON is used to reduce oxides of metals below it in the reactivity series. E.g,oxides of zinc,lead, and iron can be reduced by carbon. The carbon is usually used in the form of c...
Oct 13, 2016· Aluminium is the most abundant metal on Earth. However, it is expensive because a lot of electricity is used to extract it. Bauxite is the aluminium ore. It is purified to yield aluminium oxide
Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of
Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate

Jul 31, 2018· Lithium extraction and processing can depend heavily upon the source of the metal, so in this article, we’ll take a look at some of the more typical lithium production strategies and how they compare. What is lithium extraction? Lithium is a highly reactive alkali metal that offers excellent heat and electrical conductivity.
This slag is used as a building material, especially in road building. CaO(s) + SiO 2 (l) ————> CaSiO 3 (l) Relate the method of extraction of a metal from its ore to its position in the reactivity series. The way we extract a metal from its ore depends on the position of the metal in the reactivity series.
The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
