We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.

After extraction, the ore is processed by crushing, screening and milling. Domestic lead mine production for 1991 totaled 480,000 megagrams (530,000 tons) of lead in ore concentrates, a decrease of some 15,000 megagrams (16,500 tons) from 1990 production. Except for mines in Missouri, lead ore is closely interrelated with zinc and silver. Lead
