These deposits were formed by supergene oxidation of primary sulfide minerals during the complex interplay of ...
Sep 20, 2017 Sulfide mining is one of the ways we get metals such as copper, gold, silver and zinc. Tons of rock loaded with the metallic minerals are crushed and processed to extract the valuable metals. But that rock is also loaded with other minerals called sulfides, and when exposed to air and water they can leach acid into nearby streams and groundwater.
The Sierra Nevada Consolidated Mining Company, located in the Yreka District, Shoshone County, Idaho, was incorporated in November 1886, under the laws of the State of Oregon.

Zinc occurs only in a combined state. The dominant zinc ores found in the earths crust is zinc blende zinc sulphide or spharelite ZnS, calamine ZnCO3 and Zincite, Zno. Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed.
