Question

what are the chemical properties of metals and what is metallurgynand explain all its processes in detail i e about 150-200 wordsnRecomended if you know completely and by a expert

Answer 1

Chemical properties of metals:

• React with Oxygen to form basic oxides.
• Some metals react with water to form hydroxides.
• React with acid and bases to liberate hydrogen gas.
• More reactive metals displace less reactive metal from its salt.

The process of extracting a metal from its ore and refining is called metallurgy.

The extraction of a metal from its ore involves the following steps:

• Concentration of the ore: This process involves the removal of the undesired impurities i.e., gangue, from the ore.
• Conversion of concentrated ore to oxide: This process is usually carried out by calcination or roasting.
• Reduction of metal oxide to metal: This process is carried out by using reducing agents.
• Refining of metal: The metal is refined usually by the process of electrolysis.
