Office of Wastewater Management - Hardrock Mining Overview
Hardrock mining involves uncovering and extracting non-fuel metal and mineral deposits of solid ores or eroded deposits in streambeds. Eleven common minerals mined are copper, gold, iron ore, lead, molybdenum, phosphate rock, platinum, potash, silver, uranium, and zinc. The combined value of the eleven metals and minerals listed above was $12. ...

2018.8.3 In this empirically grounded perspective, we explore how, if managed correctly, mining might go beyond a straight conversion of finite natural capital to financial resources. We suggest a process where mineral extraction could act as a catalyst for more diversified growth and even serve as a basis to restore forms of ‘natural capital’ it had

Phosphate Florida Department of Environmental Protection
Nine phosphate mines are currently active. Nine mines are 100 percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down. Phosphate mines typically range in size from approximately 5,000 to 100,000 acres. Phosphate mining disturbs between 3,000 to 6,000 acres annually in Florida.

Mining - The Phosphate Risk
When the permitting process is complete, mine construction begins, including road building to the site. In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground.

2020.4.22 Phosphate rock is shipped to plants where it is treated with sulfuric acid, yielding phosphoric acid, which in turn is treated with ammonium to create a water-soluble fertilizer. For every ton of phosphoric acid, this process yields five tons of calcium sulfate, or phosphogypsum, which is dumped into ever-growing piles like St. James Parish’s Stack

Mineral Resource of the Month: Phosphate Rock - EARTH
The first documented phosphate rock mining took place in England in 1847, using picks and shovels. Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate

Phosphate rock formation and marine phosphorus
2011.8.1 Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and non-renewable element for fertilizer production, upon which global fertility depends.The startling limitation of phosphate rock

CPM LCA Database - Extraction and beneficiation of rock phosphate
1999.3.26 Consequently, rocks containing a large amount of CO2 are more affected. (Becker, 1989) The process of mining and beneficiation to produce one ton of commercial rock phosphate (32 % P2O5) requires approximately 0.9 GJ/tonne rock or 2.9 GJ/tonne P2O5. If the rock is calcined the total energy requirement is doubled (Ullmann, vol.
