Cobalt A Blast from the Past for Canadian Mining

This is where the small Ontario town of Cobalt enters the picture. Cobalt, located in northern Ontario close to the Quebec border, was a major mining centre for silver over 100 years ago. In the first six decades of mining there, the town's silver mining camps shipped almost 1.2 million tons of rich silver ore and concentrates.

Investigating the sustainability of the global silver

Extracting lead from silver was known from antiquity, but the extraction of silver from copper and zinc was only learned in modern times. The ore grades for copper, zinc and lead has been steadily declining for the last 100 years, now levelling off at very low content (∼1% or 100 g per tonne for copper and zinc).
