Ten representative rock samples from Kakul phosphate deposit exposed near Abbotabad, Pakistan which are used for the manufacturing of fertilizers were studied for uranium content determination with the help of ssion track and neutron activation analysis techniques. Each sample was split into three parts.
deposits). These new sources are continually investigated, as is happening now at the Hazara deposit in Pakistan (16% P2O5) and the Kohelar deposit in Iran (% P2O5) [13,14]. Upgrading processes of sedimentarytype phosphate ores consist of separating the gangue minerals (silicates and carbonates) from the valuable phosphate material [15–17].

Sep 12, 2015· That most phosphate deposits are derived from chemical precipitates and igneous sources suggests that much of the remaining 1% may have been wrongly attributed to droppings. It is more likely that these deposits on the Pacific Islands were formed in the same way as the other marine phosphate deposits.
As part of a larger study, the Geological Survey undertook a study to identify the potential for phosphate deposits in Afghanistan. As part of this study, a geographic information system was constructed containing a database of phosphate occurrences in Afghanistan and adjacent countries, and a database of potential host lithologies compiled from 1:1,000,000 scale maps.
Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.
Gemstones, also known as semiprecious stones or gems, are minerals widely used in jewelry and for ornamental and western regions of Pakistan are rich in high quality gemstones. Some of the major gemstones are enlisted below; Peridot; Aquamarine

Florida''s Phosphate Deposits. A blanket of phosphate deposits covers much of peninsular Florida. In the areas that are considered economical to mine, the matrix layer, which consists of approximately equal parts phosphate rock, clay, and sand, averages 12 to 15 feet in thickness.
Phosphorus is a mineral that combines with other substances to form organic and inorganic phosphate compounds. The terms phosphorus and phosphate are often used interchangeably when talking about testing, but it is the amount of inorganic phosphate in the blood that is measured with a serum phosphorus/phosphate test.
Phosphate rock deposits remain unexploited. ... Pakistan has an installed capacity of one million tons for production of all types of phosphate fertilisers, though being operated at 60 per cent of ...
Mineral deposit . Mineral depositMineral depositIron deposits: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world''s great mineral treasures. There are two major types of deposit.

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) fertilizer production, (c) and research laboratory of NFC (National ...
Phosphate Occurrence and Potential in the Region of ... in countries adjacent to Afghanistan, including Iran, Pakistan, Tajikistan, Turkmenistan, and Uzbekistan to aid in determining what additional types and ages of phosphate deposits might occur in Afghanistan, as well as the potential for these deposits .
In Pakistan different types of uranium deposits are identified but the first deposit that was discovered in 1959 in Dhok Pathan Formation of Siwalik sediments was a sandstone type uranium deposit and later on so many other such type of deposits are discovered. So in Pakistan study of sandstone type uranium deposits is very important.
The bulk of commercial phosphorusbased compounds are derived from marine sedimentary phosphate rock deposits, with much of the rest derived from igneous deposits. Sedimentary phosphate deposits are concentrated in two main belts, the tradewind belt that is aligned north–south from the equator to 50° latitude, and the equatorial belt ...
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 (PO 4 3–) or runoff losses from PR products like PO 4 3– fertilizers, animal feeds, and detergents could cause eutrophication of surface waters enriched in PO 4 3– by .
