Question

explanation on extraction of zinc metal from its ore metal​

Answer 1

Answer:

The most commonly available ore used in the extraction of Zinc is called ZincBlende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.

Answer 2

Extraction of zinc metal from its ore metal​:

• The most commonly found ore of zinc required for its extraction is Zinc Blende (ZnS- Zinc Sulphide).
• One can apply Roasting method for separation or extraction of Zinc.
• In this process, first of all, grind the extracted ore finely and then introduce rising stream of air through it.
• It effectively removes high quantity of sulphur and converts ZnS into ZnO (Zinc oxide).
• Then mix ZnO with coke, grind the mixture and heat at 1673K at fire clay.
• At last, ZnO is reduced to metallic Zinc and Carbon act as the reducing agent here.

The process is called Belgian process and the reactions involved here are as follows:

                              $2ZnS + 3O_{2} \rightarrow 2ZnO+2SO_{2}$

                                $2ZnO+C \rightarrow 2Zn+CO_{2}$
