World phosphate rock production in 1998 2021 [] The estimates of world production and reserves for the major worldwide producers are given in Table phosphate rock deposits have been exploited for a long time with varying intensity; therefore the distribution of the reserves does not entirely coincide with the area of their exploitation
·Ordinary least square regression method has been applied to investigate the relation between interest rate and savings &deposits in Pakistan with the help of E views statistical software The
·The Nigerian phosphate rock deposits are sedimentary in origin They occur mostly in granular nodular and vesicular forms with an average weight percent of P205 varying from to % which compares favourably with the phosphate at Hahotos Togo % Since phosphates are produced in a few countries and are consumed in most there
·The carbonatites contain more than 10% fluorapatite and the deposits contain large quantities of primary apatite and secondary phosphates Dahanayake 1995; Pitawala et al 2003 The results
·Apatite is the most abundant phosphate mineral which include more than 95% of al phosphorus in the Earth´s crust 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
·The sedimentary phosphates include marine phosphate deposits and weathered phosphate deposits The phosphogenic window Fig 1 commonly occurs at depths varying between 100 and 500 m at
Phosphorites Sedimentary Phosphate Deposits Phosphates are a major source of fertilizer and a substantial secondary source of rare elements such as uranium and vanadium Most sedimentary rocks contain at least some phosphate actually occurring as calcium phosphate in various forms of the mineral apatite but essentially bone fragments
·In some deposits Ca Fe AI and Fe AI phosphates are associated with apatite McClellan and Germillion 1980 Currently the apatites recovered from igneous and metamorphic rocks have commercial impor tance but such apatites supply only a small fraction of the world market On the other hand sedimentary phosphates
·In Pakistan the bauxite deposits are reported mainly from Salt Range and lesser Himalayas and these deposits largely occur along major unconformities Ahmad 1969 Kazmi and Jan 1997 Kazmi and
·Zircon composition has great potential as a pathfinder for porphyry Cu ± Mo ± Au systems The present study used a large integrated laser ablation inductively coupled plasma mass spectrometry LA ICP MS U Pb age and trace element dataset for both infertile and fertile magmatic suites in order to elucidate distinctive zircon signatures diagnostic of metallogenic

There are some deposits of nitrates and phosphates in earth s crust Nitrates are more soluble in water Nitrates are difficult to reduce under the laboratory conditions but microbes do it easily Ammonia forms large number of complexes with transition metal ions
The book is an important contribution to the scientific understanding of phosphate deposits as well as a valuable aid to the search for an exploitation of phosphates in many parts of the world Customer reviews Deposits Hazara Pakistan Mirza Talib
·The concentration of 32 elements was determined in phosphate rock samples from the Hazara phosphate deposits of Pakistan using instrumental neutron activation analysis INAA technique employing different irradiation protocols These included 23 major minor and trace elements Al As Ba Br Co Cr Cs Fe Ga Hf K Mn Na Rb Sb Sc Sn Ta Th U V
·northern Pakistan Fig 1 Pakistan produces 50 000 metric tons out of which about 3 000 tons are produced from the Lasbela and Khuzdar districts Most of the barites are used to make drilling mud heavy and a minor amount for paint industry The majority of barite deposits in Pakistan are consid ered as hydrothermal replacement type in
·The rare earth elements REEs content of Kakul phosphate rock PR from different localities of the main Hazara deposits of Pakistan were determined using instrumental neutron activation analysis
·These great phosphate deposits were laid down in a sea saturated with nutrients and teeming with life As a result the phosphates are crammed with the fossilised phosphatic bones and teeth of fish sharks and a host of other extinct vertebrates Fig 1 A Moroccan conveyor belt transporting the phosphate sand and rock to the processing
·deposits exist for Afghanistan the need for detailed exploration for phosphate the remoteness of some locations and the probability that a deposit would not be exposed at the surface mean that one or more deposits are not likely to be identified in the near future Even if a phosphate bearing deposit
About 95 percent of the produced phosphates are consumed in the agricultural sector as fertilizers and animal feed stocks Egypt and Sokoto phosphate deposits Nigeria Phosphates may be derived from a number of sources but the most common is the one that contains high concentration of phosphates in nodular or compact masses Fig 1
