  • How is metal extracted from ore? | Yahoo Answers

    Aug 06, 2006· Rating Newest Oldest. Best Answer: Usually through a process called smelting, whereby the ore is first crushed, then put into a large crucible (think a big pot) then heated until the metal separates from the impurities in the ore. The metal is much denser than rock, so the impurities can be poured off or otherwise removed.

  • Concentration of Ores – Study Material for IIT JEE ...

    Generally metal ores are heavier than the gangue associated with them. By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For this, either table or Hydraulic classifier is used. Generally oxide and carbonate ores are concentrated by this method. haematite and cerussite. There are two gravity concentration methods.

  • extraction of metals introduction

    Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.
