High Rock mine right overhead the mountain is pierced to its summit and large buckets were continually going up and down carrying at each trip about a ton of phosphate to the opening at the summit. These buckets are worked by machinery and the distance from the bottom of the mine to the opening at the summit is about 100 feet.
Phosphate rock is a general term referring to rock with high concentrations of phosphate minerals, most commonly those of the apatite family with the general formula Ca 5 (PO 4 CO 3) 3 (F,OH,Cl). Ninety percent of phosphate mined is used to produce chemical fertilisers.
Phosphate mining is an important part of the process of producing chemical fertilizers. The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are loed.

Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 10mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh is treated by 2stage flotation, and the fraction larger than 10 mesh is used for secondary road building.
Phosphate rock is primarily treated with sulphuric acid to produce phosphoric acid, which is either concentrated or mixed with ammonia to make a range of phosphate (P2O5) fertilizers. Potassium is the third major plant and crop nutrient. Potassiumbased fertilizers are also produced from mined ores. Several chemical processes can be used to ...
This is true for dust from our mining operations which, like the phosphate rock we mine, may contain low levels of radiation. The dust generated during the removal of rock and soil above the phosphate deposits – probably the dustiest part of mining – would be comparable to the dust generated in agricultural tilling or digging in your yard.
Source: USGS 2020 1. Phosphate rock (phosphorite) is a marine sedimentary rock which contains 1840% P 2 O 5, as well as some uranium and all its decay products, often 70 to 200 ppmU, and sometimes up to 800 main mineral in the phosphate rock is apatite, and most commonly, fluorapatite – Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 (F,OH) is insoluble, so cannot directly be used as a ...
