How should extract the low reactive and metals and middle reactivity of metals?
Answers
it is depend on How pure it is?
Answer:
Explanation:
Metals of high reactivity level
Metals in the top of the reactivity level i.e. metals like sodium, magnesium, calcium, etc cannot be obtained from their compound by heating with carbon as they are very reactive. Electrolytic reduction is used to obtain such metals.
Metals of medium reactivity level
Metals in the middle of the reactivity series i.e metals like lead, zinc, copper, etc are moderately reactive and are generally present as carbonates or sulphides. Sulphides ores are converted into oxides by heating strongly in the presence of excess air. Sulphur impurities can escape as gas, this process is known as roasting. Carbonates ores are calcinated to eliminate carbonate and moisture impurities. Calcination is a process where the ore is converted into oxides by heating strongly in the presence of excess air.
Metals of low reactivity level
Metals that aren’t very reactive are placed low in the reactivity series. These metals can be reduced to metals by heating alone. For example, Mercury is procured from its ore, cinnabar (HgS), by the process of heating. Copper can also be obtained from its sulphide ore (Cu2S) by heating.
