The Thacker Pass lithium mine is a lithium clay mining development project in Humboldt County, Nevada, which is the largest known lithium deposit in the US and one of the largest in the world. [ 5 ] [ 6 ] [ 7 ] There has been significant exploration of Thacker Pass since 2007.
The sulfur is recovered in the form of sulfuric acid. Sulfur recovery from smelters rose from 544,000 metric tons in 1970 to 1,403,000 tons in 1980, due to tightened air emissions standards. Sulfur recovery peaked in 1988 at 1,610,000 tons, then declined to 730,000 tons in 2014, coinciding with a decline in the U.S. metal smelting industry.
The sulfur mine is notable for being the highest mine in the world at 5,950 metres (19,520 ft) [28] and the highest permanently inhabited area. [8] An expedition in 1935, part of the International High Altitude Expedition, found that miners lived at an altitude of 5,300 metres (17,500 ft) in the town of Quilcha and reached the higher mine on foot.
The decrease in water levels (because of construction of upstream dams and unknown causes), the increase of sedimentation (from catchment erosion), organic pollution (from food processing and Burdur City raw sewage waste), and inorganic effluent (from a sulphur mine) represent long-term threats to the integrity of the lake.
Human activity at the site was primarily concerned with production of sulfur, which was discovered in 1917. Sulfur mining and ore milling operations occurred at Crater intermittently from 1917 through the late 1960s, with a population that peaked at 36. The buildings of the town have been torn down, but the mining equipment remains.
