 · The major source of phosphorus for the manufacture of fertilizers is rock phosphate, ... sludge dewatering liquid (Simoes et al. 2018), poultry manure (Yetilmezsoy and SapciZengin 2009), dairy manure (UludagDemirer et al. 2005), sewage sludge (Uysal et al. 2010), and landfill leachate (Li and Zhao 2003). P recovery as struvite from these sources not only solves the problem of global P ...

Radioactivity elements in phosphate rock. The radioactivity of phosphate rock was probably first observed in 1908, when the British physicist R. Strutt found that samples of phosphorite were many times more radioactive than the average rocks of the Earth's crust. 23 The dominant radioactivity detected in phosphate rocks are uranium, thorium and their decay products in equilibrium with their ...

 · Dewatering of Phosphatic Clay Waste. Phosphatic clay waste generated during the mining and beneficiation of phosphate ore is disposed of by impoundment behind earthen dams. The overall natural settling rate of phosphatic clay waste is extremely slow ( Bureau of Mines, 1975). Generally, the clay wastes have a rapid initial settling rate ...

Phosphate rock is one of the basic mate rials for fertilizers. About 90 % of the About 90 % of the phosphate rock output in the world is used fo r fertilizer production.

Phosphate rock contains radionuclides in concentrations that are 10 to 100 times the radionuclide concentration found in most natural material. Most of the radionuclides consist of uranium and its decay products. Some phosphate rock also contains elevated levels of thorium and its 7/93 (Reformatted 1/95) Mineral Products Industry daughter products. The specific radionuclides of ...

First, phosphate rock, from which P fertilizers are manufactured, is a finite, nonrenewable resource, and it must be used efficiently in order to maximize its life span. Second, there is a need to maintain and improve the P status of many soils for the growth of crops for food, fibre and bioenergy. This is particularly important

Phosphate rock is also used as a raw material for animal feed supplements and for industrial appliions. Benefits. When a watersoluble P fertilizer is added to soil, it quickly dissolves and reacts to form lowsolubility compounds. When phosphate rock is added to soil, it slowly dissolves to gradually release nutrients, but the rate of dissolution may be too slow to support healthy plant ...
