The exploration and mining of Nigerian barite are primarily by artisanal and small-scale miners (ASM) whose operations are characterized by poor productivity. As a result, the quantity and quality of barites produced do not satisfy the nation's oil sector demands and other industries that require the mineral. This situation leads to massive importation of the mineral with negative impact on ...

Lead - PUB0659 | Missouri Department of Natural Resources

Commodity Lead is a soft, very dense, ductile, malleable, and corrosion-resistant metal. Lead currently is produced in Missouri from multiple mines in the southeastern part of the state, where it is found associated with zinc, copper and silver. Lead was named from the word "plumbum," Latin for "liquid silver," and which provided the source for lead's chemical symbol of Pb.

The Dee North mine, Elko County, Nevada. - Free Online Library

Bedded (massive) syngenetic lenses of barite which are also common throughout the sediments have been one of the United States' premier sources of industrial barite. In fact, in the vicinity of the Dee North and Meikle mines, numerous surface prospects and pits were exploited for bedded barite during the "barite boom" of the 1950's.
