High reactive metals such as aluminium, calcium and sodium are extracted from their ores by the electrolytic reduction. These highly reactive metals cannot be reduced by using carbon as it is less reactive. In this method the electric current is passed through the ores to get the pure metals.

2019-12-6 The reason behind presence of metals in form of ores and minerals is that, most of metals being highly reactive, cannot exist in free form [6]. Ores have usually high traces of metals to be extracted and that’s why these ores are of major importance in metal industry. Table below shows common ores of some metals

Metals high up in reactivity series are extracted by electrolytic reduction. While those in the middle are extracted first by converting into oxide and then reducing by carbon. 1 Same method cannot be used because metals have more affinity for oxygen than carbon. Molten sodium chloride is taken for

2013-8-19 The depletion of high grade ore reserves has resulted in technology research increasingly looking at ways of extracting metals from low grade ores which were previously uneconomic to use. The crucial point is thatgenerally speaking, the method of extraction depends on the metals position in the reactivity

2021-3-18 The metals high up in the reactivity series generally occur in the form of their oxides which are quite stable and cannot be extracted by reducing the oxides with carbon. On the other hand, the metals in the middle of the reactivity series occur in the form of carbonates and sulphides which are first converted into oxides by various methods and ...

Extraction of metals: The process of obtaining pure metal from its ores involves a series of steps which together known as extraction of metals. On the basis of their reactivity series metals can be grouped into three categories. (i) Metals of low reactivity (ii) Metals of medium reactivity (iii) Metals of high reactivity.. There are separate steps for these groups for obtaining pure metals.

2017-3-27 Extraction of Metals. History ().. After the Bronze Age came the Iron Age. People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore. The extraction of iron today is done in a blast furnace.. The Iron Age began in Asia and Africa in 1,100 B.C. and came to Britain in 500 B.C. In many ways, we are still in the Iron Age - take a look around.

2020-8-18 The ions of low ranking metals are readily reduced by high ranking metals on the reactivity series. Therefore, low ranking metals are easily displaced by high ranking metals in the single displacement reactions between them. A great example of such a reaction is the displacement of copper from copper sulfate by zinc.
