Lead and Zinc Energy

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Extraction of Zinc: Process, Ores, Diagram Embibe

Jan 17, 2022 Zinc can be extracted from its carbonate ore (calamine) through calcination. The steps are- 1. Concentration of Ore Calamine is converted into its oxide form by heating the ore strongly in the absence of air. This process is known as calcination and produces zinc oxide and carbon dioxide gas. Z n C O 3 ( s) → Z n O ( s) + C O 2 ( g) 2. Reduction
