Galena ore.

Galena value: Some mines producing galena produce more revenue from the silver content of their ore than from the lead content. Assume that we have a mine that produces argentiferous galena with an average composition of 86% lead, 13% sulfur, and just 1% silver (as shown in the diagram on the left).Galena (an ore) is partially oxidized by passing air through it at high temperature.
