Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.

The ore extraction could be underground or open pit which is the most common method. The main phosphate rock extraction stages in open pit are drilling, blasting, excavating, loading, haulage and dumping.

The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. The ...
The company also mined blue rock phosphate at Swan Creek and Gordonsburg, both in Lewis County, and the Swan Bluff area in Hickman County. In 1896 Judge S. O. Weatherly discovered brown rock near Mt. Pleasant. This site contained brown phosphate rock of high grade and proved to be one of the most important mineral discoveries in Tennessee.
of phosphate rock mining and processing has occurred at numerous sites around the world over the past few decades. Vertical integration of phosphate rock mining and processing may be a necessary component to compete in the world phosphate fertilizer market when new deposits are developed.
In 2015, 27.6 million 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 Morocco.The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion.. As of 2015, there 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 30-40 feet below ground.
Phosphate-mining production is expected to grow by 2 percent through 2020. Find out which countries produced the most phosphate last year. Phosphate and potash are primarily used to produce ...
following describes the general mining and processing steps for both then followed by specific steps for each. 8.1.1 Phosphate Rock Mining The primary method of mining and exploration of phosphate rock is surface mining. Surface ... Energy and Environmental Profile of the U.S. Mining Industry Phosphate Reduction
In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid. In the process, sulfuric acid is added to the phosphate to create phosphoric acid — which is easily absorbed by plants. Phosphogypsum (or "gypsum"), a radioactive material, is a byproduct of this process.

about phosphate rock basics, mining and beneficiation, the association of toxic metals and radioactive elements in the phosphate rocks and the transfer pathways of these hazardous elements from the phosphate rocks to the environment. The discussion part was mainly concerned on the environmental impact of phosphate mining and processing
In Florida, after the phosphate rock is extracted, the ore is dumped into a pit at the mine site, and high-pressure water guns turn it into slurry. The slurry is pumped to a beneficiation plant. At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles.
