About this site

Lead-bearing ore is mined from underground or open pit mines. 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.
