Question

Extraction of medium reactivity metals!
Class 10 Science ( Play elaborate in a easy way )

P.S: If you don't have the answer then don't write..
I will mark you the brainliest if you provide me with a easy but nice explanation!

Answer 1

metals that are in middle of reactivity series they have two kinds of course that is carbonate Ore and sulphide ore for extracting metals from carbonate Ore calcination is the process first the overhead to be calculated and from sulphide over roasting is the process later oxide of the metal is reduced into the metal and it is se send to refinery for purification.

Answer 2

The metals present at middle are extracted from their ores by the process of roasting or calcination

Roasting - The sulphide ores are converted into oxides by heating strongly in the presence of excess of air

Calcination- The carbonate ores are converted into oxides by heating in limited air.

After roasting or calcination these metal oxides are reduced using suitable reducing agents
