Gravity Separation This method is based on the difference in the gravities of ore and gangue particles. Magnetic Separatio n A powdered ore is carried through a conveyor belt that runs over two rollers, one of which is magnetic, in this operation. The magnetic particles are attracted to the magnetic roller and fall down first, followed by the non magnetic particles.

17/01/2022ยท In this method, the powdered ore is placed over a leather belt which moves over two rollers, one of which is magnetic. When the crushed ore is passed over the magnetic roller, magnetic ore particles are attracted by it and fall below it while impurities fall away from the magnetic roller.
Q.1. What are the methods of extraction of metals?Ans: There are three main methods of extracting metals from ore. They are by electrolysis, reducing an ore by a more reactive metal, reducing the o...Q.2. What type of chemical reaction is used to extract metals from ores?Ans: The chemical reaction used to extract metals is decomposition reaction, carried out by electricity, extracts metals from their naturally occur...Q.3. How is a metal extracted and processed?Ans: Although other non ferrous metals have lower melting points than aluminium and can therefore be processed at somewhat lower temperatures, the...Q.4. What is the major source of metals?Ans: Rocks and soils are the principal natural sources of heavy metals in the environment. The primary rocks, which are called magmatic or igneous...Q.5. What are the steps involved in the extraction of metals from ores?Ans: The extraction of a metal from its ore involves mainly three stages. They are Enrichment or concentration of ore, Extraction of metal from con...
