The negotiations to pursue rights to the phosphate involved four parties: the British and German governments, the newly reorganised Pacific Phosphate Company, and Jaluit-Gesellschaft (a German mining company that had been ...
The effects of phosphate mining in Nauru have had significant negative impacts on the island's environment and economy. [1] One of the most prominent effects of the phosphate mining in Nauru is the extensive environmental degradation that has occurred as a result of the extraction of phosphates. [ 2 ]
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion , sinkholes , loss of biodiversity , or the contamination of soil , groundwater , and surface water by chemicals emitted from mining processes.
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. The eastern phosphate deposits are mined from open pits. The western deposits are mined from both surface and underground mines.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
In 1977 the United States Environmental Protection Agency published a position paper advocating for a phosphate ban in detergents.. States including Maine, Florida, and Indiana in the United States began restricting or banning the use of phosphates in laundry detergent in the early 1970s, culminating in a nationwide voluntary ban in 1994.

These contain the waste byproducts of the phosphate fertilizer industry. The United States Environmental Protection Agency (EPA) has banned most applications of phosphogypsum having a 226 Ra concentration of greater than 10 pico curie /gram (0.4 Bq /g) [ 7 ] in 1990. [ 3 ]
The mining industry of Morocco is important to the national economy. Morocco is the world's largest producer of phosphate , and contains about 75% of the world's estimated reserves. [ 1 ] Mining contributed up to 35% of exports and 5% of GDP in 2011. [ 2 ]
