Apr 26, 2017· Ore in Algeria and Tunisia was discovered in 1873 and mining initiated in 1889. Production from the large Moroccan deposits, first identified in 1914, began in 1921. The guano phosphate deposits in the Pacific Islands were found in the 1890s and mining commenced in 1900 on Ocean Island, in 1906 on Nauru Island and in 1908 on Makatea Island.

Rock phosphate deposits contain many million tonnes of uranium, which may be extracted as a by-product of making fertilisers. Some 20,000 tonnes of uranium has already been obtained from these rock phosphate deposits, but the process became uneconomic in the 1990s. Higher uranium prices and process refinements have changed the economic situation.

Sedimentary, marine phosphate rock deposits provide 75% of the world's phosphate resources, while 15 – 20 % come from igneous and weathered deposits and only 1 – 2% from biogenic (mainly from and bat guano accumulations) resources (van Straaten, 2002). In Nigeria, the phosphate deposits are of the sedimentary, marine origin.
