How Zinc Ore Is Mined

Zinc processing Ores Britannica

The geology of zinc deposits is complex. In most cases, hydrothermal mechanisms have occurred in which aqueous solutions were forced through porous strata at high temperatures and pressures to dissolve zinc, lead, and other minerals, which were finally precipitated as sulfides. The zinc content of mined ore is usually between 3 and 10 percent.

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.

Zinc: smelting, producing and classification-Metalpedia

Zinc is found in the earth’s crust primarily as zinc sulfide (ZnS). Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from

Lead and Zinc Mining Encyclopedia of Arkansas

Sphalerite (zinc sulfide, containing sixty-seven percent zinc) and smithsonite (zinc carbonate, containing forty-eight percent zinc) were the two most commonly mined zinc ores in Arkansas. Historically, zinc was used as an alloy to make brass, rolled into sheets for roof cladding, melted for “hot dip” and other galvanizing, and pulverized

New Jersey Mines Mining Artifacts

By far the dominant ore minerals at Sterling Hill are franklinite (a zinc-iron oxide), willemite (a zinc silicate), and zincite (zinc oxide). Most of the underground mining of these ores postdates the "Great Consolidation" of 1897, when disparate mining interests at Sterling Hill and Franklin were united under the New Jersey Zinc Company.
