The small island nation of Nauru and its neighbor Banaba Island, which used to have massive phosphate deposits of the best quality, have been mined excessively. Rock phosphate can also be found in Egypt, Israel, Western Sara, Navassa Island, Tunisia, Togo, and Jordan, countries that have large phosphatemining industries.
The Mining Process. The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits. Information like the location, size, and shape of the ore is determined to focus the mining effort. Hundreds of boreholes are drilled and thousands of core samples studied and tested to gather information ...

Oct 17, 2019· Phosphate mining involves the extraction of ores containing chemical compounds rich in substances that contain the phosphate ion. These ores vary in their composition, and different varieties of phosphate rock require different mining techniques. Processing of the mined ore follows extraction.
For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 3032% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which superphosphates are produced. The fertilizer market is very competitive.
The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US billion. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Ido, and Ut. The eastern phosphate deposits are mined from open pits. The western deposits are mined from both surface and underground mines.
(2) Although many sources of mining activity are located in remote areas, nearly every state has significant quantities of mineral processing wastes. Waste Rock. Large amounts of waste rock are produced from surface mining operations, such as openpit copper, phosphate, uranium, iron, and taconite mines.
Conda/Woodall Mountain Mine Site. Southeastern Ido is a major phosphateproducing region, and phosphate mining has been an important industry in the area since the early 20th century. The process of mining phosphate ore resulted in open pits and piles of waste rock overburden (materials covering the phosphate ore).
