Phosphate mine dump stablility and revegetation.
Eugene E. Farmer
Written in English
Reclamation efforts in western phosphate mines are examined by addressing stabilizing factors, such as waste dump site selection and construction, soil erosion and mass stability, and by outlining successful revegetation procedures.

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. World Phosphate Rock Reserves and Resources Executive Summary The amount of remaining phosphate rock reserves and resources worldwide has become an issue of speculation. It has been hypothesized that phosphorus (phosphate rock) production will "peak" in and then production will unavoidably decrease as the reserves are depleted.
Geoffrey Blight, in Waste, Mine wastes and their environmentally acceptable storage constitute the largest waste problem on the planet. Mine wastes have been accumulating for thousands of years, and their rate of production has accelerated in step with increases of the human population to an estimated world-wide production rate of × 10 9 ta Proposed changes in mining policy to hit steel companies with captive leases 04 May, , AM IST. The proposals are beleived to have been submitted to the PM’s Office to double the sector's contribution to GDP, from Rs lakh crore in fiscal year .
The West Coast Environmental Protection Association fears a new phosphate mine at Elandsfontein could cause irreversible damage to the ecologically sensitive Langebaan Lagoon. From here north for approximately 40 miles the parkway passes through or near a geologic region of limestone rich in phosphate deposits. Abandoned mine shafts in limestone ledges on both sides of the parkway in this immediate area are silent reminders of past mining activity.

Chemical properties. The phosphate ion has a molar mass of g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, HBeilstein Reference: 5.

Inmillion metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and phosphate mining industry employed 2, people.
The value of phosphate rock mined was US$ billion. As ofthere are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah. 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 feet below ground.
Four Corners Lonesome Mine_DEP Staff Jessica Duke_Dragline Phosphate Mining Florida's Phosphate MinesThere are 27 phosphate mines in Florida, covering more thanacres. Nine phosphate mines are currently active.
Nine mines are percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down. Phosphate Mine Dump Hydrology by Eugene E.

By extending existing mining operations onto adjoining properties, we can continue producing phosphate in the area without increasing our water consumption by connecting to existing stormwater and water circulation systems.
Reclamation is the process of returning the land and water to a usable condition once mining has ceased. Because of the complete destruction that takes place during mining activities, the goal of reclamation is to bring the land back to a place that will allow natural processes to begin again.
Jadwiga Szczepańska, Irena Twardowska, in Waste Management Series, III Mining waste sources and amounts. Mining waste is the high-volume material that originates from the processes of excavation, dressing and further physical and chemical processing of wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods.

Biosolids Using Organic Phosphate For the Oronogo-Duenweg site, biosolids initially worked well to establish plant growth. Approximately 40–60 tons/acre dry weight of biosolids was applied to select site areas.
Revegetation was highly successful over the next. Phosphate mining is a major industry in Florida, but it’s also a major source of pollution, responsible for red tide, toxic algal blooms and killing wildlife. In the northern part of the state.

The sand is sent back to the mine site to be used in reclamation and the phosphate is sent to the chemical processing plant where it is processed for use in fertilizer and other products.
