Ask us

Limestone uses — Science Learning Hub

Calcium oxide, obtained from limestone, acts as a pH regulator when extracting gold from quartz. The chemical extraction of gold from powdered quartz rock uses a solution of sodium cyanide. In this cyanidation process, the pH of the solution needs to be maintained between 10–11 to prevent the production of deadly hydrogen cyanide gas.

UM Geologist Describes Where the Gold Comes From

At first glance, Bannack must have seemed an unlikely place to look for an ore body. The pebbles and boulders along the creek are limestone, a specimen that rarely contains gold. And since there is no gold upstream from Bannack and very little downstream, the source of the bedrock gold must be within the cliffs above the area.
