Various types of minerals, present in phosphate rock of Hazara area of Khyber Pukhtoonkhwa Province of Pakistan, were identified and their concentration was determined using a suitable method.
Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and non-renewable element for fertilizer production, upon which global fertility depends.The startling limitation of phosphate …
Samples of phosphate rocks were collected from (a) the deposits of phosphate rock near the city of Abbottabad in Hazara division of Pakistan, (b) the phosphate fertilizer manufacturing plant at Haripur in district Abbottabad where local and imported phosphate rock is used as a raw material for SSP (Single Super Phosphate) …
Despite the known and proved reserves of over 7 million tons of good quality rock phosphate deposits in Hazara the production is very low. Pakistan's rock phosphate …
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.
The low metamorphic Khyber-Hazara Zone contains phosphate, soapstone, marble, quartzite, gypsum, iron, manganese, coal, etc. ... Pakistan h as larg e deposit s of Cu b ut import ing so f ar.
This study sheds a light on the depositional environment of the late Cretaceous phosphorite deposits that belong to Amman/Al Hisa Formation. The genesis of phosphorus supplied to the oceanic reservoir is still controversial, either it came through weathering of pre-existing rocks or through upwelling of deep cold water bodies. For a …
The concentration of 32 elements was determined in phosphate rock samples from the Hazara phosphate deposits of Pakistan using instrumental neutron …
Morocco holds the world's largest deposits of sedimentary phosphate rocks, and also possesses several alkaline complexes with the potential to bear igneous phosphate ores that are still largely ...
We present a review study which deals the uranium deposits in Pakistan by describing their regional distribution, formation of deposits, source and the host rock, alterations in host rocks and the ...
The major phosphorite deposits and phosphate rock potential in Saudi Arabia are essentially found in northern part of the country; the area is known as the "Sirhan-Turayf region". Other phosphate-bearing areas (the Red Sea, central and eastern regions) are not so economically important.
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 (INAA). 25 phosphorite samples were collected from different phosphorite sites and 6 samples representing different batches from the …

Phosphate Deposits By V. E. McKELVEY CONTRIBUTIONS TO ECONOMIC GEOLOGY GEOLOGICAL SURVEY BULLETIN 1252-D A summary of salient features of the geology of phosphate deposits, their origin, and distribution UNITED STATES GOVERNMENT OFFICE, WASHINGTON : 1967
Volume 2 contains 93 chapters contributed by 111 researchers, dealing with most, if not all, of the major individual deposits or phosphate fields of the world, whether of igneous or sedimentary origin. Total resources of phosphate rock are extremely large, but are unequally distributed geographically and only a relatively small proportion can ...
Phosphate rocks (PRs) play a crucial role in ensuring the availability of phosphorous for the world's food needs. PRs are used to manufacture phosphoric acid in the wet process as well as P-fertilizers. The chemical and mineralogical compositions ...
Estimated phosphate ores in Pakistan are 26 million ton of different range, low, average and high grade. In past, different methods were used for upgradation of phosphate ore worldwide.
Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause …

The rock phosphate deposits of Hazara are the only known commercial deposits occuring in Pakistan. These deposits, after their discovery by Latif [1] have been studied by …
Five major types of phosphate sources in the world are as follows: marine phosphate deposits, igneous phosphate deposits, metamorphic deposits, biogenic deposits, and phosphate deposits as a result of weathering.
The present paper focuses on the phosphate-bearing deposits that represent promising geologic resources for mining and sustainable development in central Egypt. Phosphates are important for ...
The world's phosphate ore reserve nearly totals 69.5 billion tons (2019), but its distribution is uneven, more than 80% of which is concentrated in North Africa. Especially, Morocco and Western Sahara are the world's richest countries in phosphate resources, with reserves of 50 billion tons in 2019, accounting for nearly 72 percent of …
The present paper focuses on the phosphate-bearing deposits that represent promising geologic resources for mining and sustainable development in central Egypt.
Countries With the Largest Phosphate Reserves An open phosphate mine. Phosphate rocks are found across the world both in sedimentary and ingenious deposits. Phosphate is used to produce fertilizer that is essential in replacing the phosphorous that is removed by plants from the soil. Phosphate rocks are mainly mined …
