Lead and ZincEnergy

6.1 Process Overview 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.


Describe the Extraction of Zinc Metal from Its Sulphide

Zinc blende (ZnS) is the sulphide ore of zinc. The extraction of zinc from zinc blende involves two steps. First, the concentrated zinc blende is converted to its oxide (by roasting). After this, the oxide is reduced to zinc metal. The reactions for the two processes are: 1.


ZincCreate WikiFandom

Zinc is an ore found at any height from surface to bedrock. It is used for mainly crafting Brass, but can be used to also make Andesite Alloy. Its forms include: Zinc block, Zinc nuggets, Zinc ore, and Crushed Zinc Ore.
