are the methods of extracting metals from their ores

Extraction of MetalsThe chemical reactivity of metals also determines their method of extraction Native metals undergo physical separation processes, such as froth flotation Froth flotation uses detergents to create floating bubbles that adhere to metal particles, while other materials settle out and are removed separately Metals with an intermediate reactivity.extraction of metals from ores using electrolysisGCSE CHEMISTRY

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 aluminum, copper, iron and titanium are given in separate pages in this section.How are metals with different reactivities extractedMetals can be arranged in order of reactivity by observing their reactions with water, acid and displacement reactions with other metal compounds This determines how it is extracted from its ore.Why do we extract metals from their ores?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.How many methods are there to extract metals from ore?May 01, 2019· The ancients were very adept at finding ways to extract metals from or Doubtless, much of their efforts arose from chance and good luck, paying attention to what happened to rocks of different types when they were used for heating pottery or.methods used to extract metals from their oreExtracting a metal from its ore

The knowledge of how to extract metals from their ores has played an incredibly important role in every known civilization The ability to make coins, tools and weapons from metals has changed the way lives are lead The first metal to be used in many areas of life is thought to be copper in around 4,000BC.Metals THE EXTRACTION OF METALS FROM THERE ORESThe 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 reductionwith carbon or carbon monoxide Thus the method of extraction of a metal from its ore depends on.

Types of Extraction

Methods of extraction Many metals are found in the Earth's crust as or An ore is usually a compound of the metal mixed with impuriti 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.
