    Guilbert and Park in their book The Geology of Ore Deposits 4 report that 76% of the world’s phosphates are regarded to have formed by chemical precipitation on the continental shelves. 23% of global phosphate deposits are derived from igneous rock sources, including carbonatite (a rock formed from molten carbonate). Personal contact was made with the managers of each of the companies involved in Tennessee phosphate mining and beneficiation. Historical data, resource and reserve estimates, along with production and cost estimates were prepared for four operating deposits and two inactive deposits.

High-grade deposits formed as a result of hydraulic concentration of phosphate grains to form granular beds with minimal gangue. The amalgamation of these beds into decameter-thick, stratiform ore zones is generally focused along the maximum flooding surface, which is a primary exploration target in upwelling-related by: Map showing phosphate deposits and distribution of upwelling water and related phenomena in modern oceans _____ 7 in.

The seventh chapter of this book provides brief description of sedimentary and igneous phosphate rocks and introduces basic ideas for characterization and classification of phosphate rocks. The chapter continues with description of biogenic apatites, description of phosphate rocks.

Florida’s phosphate rock deposits are believed to have originated in several ways. Some of the phosphate may have formed when conditions in the seawater caused dissolved phosphorus to solidify, a process scientists call precipitation.

As material settled to the bottom of the shallow coastal waters, it became part of the sedimentary layers.

The phosphate discovered in central Florida, however, quickly overshadowed other sources because the cost of mining in Florida was much lower, the deposits were much more extensive, and the phosphate content of the Florida rock was greater. Currently U.S. phosphate mining takes place in Florida, North Carolina, Idaho and Utah.

Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus.

Most of the world s phosphate deposits can be grouped into six types: 1) igneous apatite deposits; 2) marine phosphorites; 3) residual phosphorites; 4) river pebble deposits; 5) phosphatized rock; and 6) guano. The igneous apatites and marine phosphorites form deposits measurable in millions or billions of tons; the residual deposits are measurable in thousands or millions; and the other types.

The book thoroughly explains the methods used in beneficiation of different types of phosphate ores for use in the wet process. The mineralogical properties of the two major types of phosphate deposits, sedimentary and igneous, are described along with the processing methods.

Resources as unprocessed phosphate rock of varying grades or concentrate. Including hypothetical resources based on the area limits of the deposits, Morocco resources may be aboutmmt.

Phosphate rock deposits can be sedimentary or igneous, but more than 80 percent of the world’s current production of phosphate rock is mined from sedimentary deposits formed by deposition of phosphate-rich materials in marine environments. Large sedimentary deposits are located in China, the Middle East, northern Africa and the United States.

This report is the most pdf compilation of phosphate mines, deposits, pdf occurrences known. However, it is highly likely that there are additional phosphate sites that are not included. In addition, data for many of the sites are incomplete. Determination of latitudes and longitudes for some sites were impossible given the available : Chernoff, Carlotta B.

Orris, Greta. J.Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks.
