Concerns Over Sulfide Mining Resurface With Tiffany's Bill

Sep 20, 2021Sulfide 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.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
