Watch the Sunset at the Old Belmont Mine
Berkeley Pit Viewing Stand
The Berkeley Pit is a former open pit copper mine begun in 1955. It is one mile long by half a mile wide with an approximate depth of 1,780 feet. The pit is named for the Berkeley Mine, once a famous lode-mining producer in the Meaderville area. Mining was halted in the Berkeley Pit in 1982 but was resurrected in 1986 at the Continental Pit located east of the Berkeley. The main types of ore recovered from open pit mining are copper and molybdenum and in lesser amounts, gold, silver, lead and zinc. Moly-what?
Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades. Molybdenum disulfide is used as a lubricant additive. Other uses for molybdenum include catalysts for the petroleum industry, inks for circuit boards, pigments and electrodes.
