Zinc is extracted from zinc blende. The zinc blende is roasted. The solid product is mixed with coke in a blast furnace from which zinc vapours emerge.
Write the equation for the roasting of zinc blende.

Explanation

To write the equation for the roasting of zinc blende, we need to understand the process involved. Here’s a step-by-step solution:

### Step 1: Identify the Chemical Composition of Zinc Blende
Zinc blende is primarily composed of zinc sulfide (ZnS).

### Step 2: Understand the Roasting Process
Roasting is a process in which a sulfide ore is heated in the presence of air. During this process, the sulfide is converted into an oxide, and sulfur dioxide gas is released.
