150-2 most important economically being the El -Sebaiya (west Mahamid) and El Mahamid deposits near El Sebaiya. Because of the increasing world demand for phosphate, P 2 O 5 content of the ore is gradually falling, and it is becoming economical to mine and beneficiate many lower-grade deposits (El-Jalead et al., 1980).

122 . PHOSPHATE ROCK (Data in thousand metric tons unless otherwise noted) Domestic Production and Use: Phosphate rock ore was mined by five firms at 11 mines in four States and processed into an estimated 27.7 million tons of marketable product, valued at $2.1 billion, f.o.b. mine. Florida and
The source of the gypsum's radioactivity is the presence of uranium, and uranium's various decay products (i.e. radium), in raw, phosphate ore. As noted by the Sarasota Herald Tribune "there is a natural and unavoidable connection between phosphate mining and radioactive material.
Local land owners are determined to mine it, but environmentalists vow to stop them before they can begin. The environmentalists point to Central Florida, where strip mining for phosphate has polluted water and air for decades. A county permit is all that stands in the way of the strip mining project.
In a review concerning such raw materials (phosphate ores, Zirconium, various metal ores) basic information on major companies involved, quantities produced, range of radionuclide concentration, chemical processes, products and by-products has been compiled for EU member states.
8.1.1 Phosphate Rock Mining The primary method of mining and exploration of phosphate rock is surface mining. Surface mining consists of clearing the site of brush, initial removal of topsoil and overburden, ore removal, and reclamation. Eastern phosphate comes from surface mining and is sometimes extracted through a mechanized
Historic phosphate mining operations involved removal of soils and rock to access the phosphate ore. As ore was excavated, overburden rock and waste shales containing selenium were excavated. This overburden and waste shale were placed adjacent to mine pits, or backfilled into pits.
The average uranium content in phosphate rock is low at 50-200 parts per million (ppm) or 0.005-0.020 percent. For comparison, some Canadian commercial rich ores have up to 15 percent or 150,000 ppm in uranium. Yet some low concentration ores are being mined in countries that are short in the high grade ores. For instance, mines at
chemical processing of phosphate ores. The key to understanding the association between environmental pollution and phosphate rocks lies in appreciating the mining and processing effect of phosphate ores. Phosphorus is normally produced by mining and beneficiation of Phosphate ores. 3 Mines produce large amounts of waste including toxic

Phosphate ores are worked by open-pit and underground-mining methods: friable phosphorites, such as those in the Baltic republics, are worked by geotechnological methods. Various methods for concentrating phosphate ores exist, and the selection of a particular method depends on the mineral composition and the structure and texture of the ore.
