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.

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 the other minerals.
