Question

How will you get metal from concentrated ore? ​

Answer 1

Answer:

Metal extraction involves the refining of metals from the gangue it is found with. Extraction of metals occurs over three major stages.

1. Concentration of Ore

1. Isolation of metal from concentrated Ore

1. Purification of the metal

Isolation of metal from concentrated Ore involves the refining of metals from the compounds it is found with to its original state. The concentrated ore is first converted to an oxide after which metal extraction is done by reducing it from an oxide to metal using a suitable reducing agent.

In this process, metal refining is done by heating the ore in a limited supply or absence of air. This is done with the aim of bringing about thermal decomposition and remove volatile compounds from the ore leaving behind a metal oxide.

Fe2O3.xH2O(s)  −→−−−▲ Fe2O3 (s) + xH2O(g)

CaCO3.MgCO3(s)   −→−−−▲ CaO(s) + MgO(s) + 2CO2(g
