How Zinc Is Made. Zinc ore is sometimes mined in conjunction with silver or lead addition to the ore itself, oil and sulfuric acid are required for the breakdown of the ores and electricity, coke, or natural gas are needed to provide the heat energy for flotation 2 zinc can be produced by a process called froth flotation, which is also.
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. The use of underground or surface mining techniques depends on the proximity of the ore body to the surface ...
Zinc Mining 80% of zinc mines are loed underground, 8% are of the open pit type, with the remainder a combination of both. In terms of production volume, underground mines account for as much as 64% of overall zinc production, combined underground/open pit mines provide 21%, and the remaining 15% is sourced from open pit mines. Rarely is the ore, as mined, rich enough to be used directly by ...
