Phosphorus is common within geological materials. The average continental crust contains 0.27% P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores.
Naturally occurring mineral products having sufficient phosphate content to be of commercial value are classified as phosphate rock. The grade or phosphate content of these products has been traditionally reported as percent Ca 3 (PO 4) 2, which is referred to as bone phosphate of lime (BPL), tricalcium phosphate (TCP), or triphosphate of lime (TPL).). …

The form of a phosphate mine waste rock pile depends on two criteria: the disposal method (top-down or bottom-up) and the land surface (flat or horizontal) (Blight, 2009).Different configurations of the mentioned criteria are illustrated in Fig. 3.The top-down disposal method involves discharging waste rock over an advancing face (Fig. 3 A–C-D).). …
Introduction. With the expected commencement [1] of fertilizer facilities with TSP, DAP and NPK plants in 1990, the phosphoric acid needs of Saudi Arabia are expected to be around 250.0 tons P205 per year.A new phosphoric acid plant seems in prospect using the phosphate rock from the Sirhan Turayf region in the north and sulfuric acid produced as a by …

The phosphate recovery chain can be divided into three processes. Starting with the extraction process where the phosphate rock is separated from the associated minerals of guange and sent to the beneficiation plant. In this second process, the phosphate rock is concentrated using physical and chemical separation methods.
El-Nasr Phosphate Company, Egypt, is processing phosphate rock in El-Mahamid Beneficiation Plant (EMBP) to a rate of 250 t/h. Water is used in thi s plant at the amount of 750 m 3 /h.
introduction : Phosphate rocks are vital non-renewable resources and are essential components in agricultural fertilizers and phosphorous-based chemicals [1-4]. About 95% of the phosphate produced around the world is consumed in fertilizer industry [5, 6]. Phosphate deposits can be divided into three groups (і) sea sediments, (іі) igneous and (ііі) biogenetic deposits [7].
In the chemical processing plant, the combined pebble/concentrate rock product is reacted with sulfuric acid producing a relatively concentrated phosphoric acid and phosphogypsum waste. ...

Approximately 70% of the 138 million tonnes of phosphate rock produced worldwide in 1980 originated from mines in the United States, the U.S.S.R., and Morocco. Work is in progress in many areas of mining, beneficiation, and chemical processing directed at solution of the present and future problems facing the phosphate fertilizer industry.

Mined phosphate rock is sold to phosphate processing plants that digest the rock using sulfuric acid to make phosphoric acid. The vast majority of phosphoric acid is used in the production of fertilizers to grow the food the world needs; additionally, phosphoric acid is also used as an additive in livestock feed and even in food products.
The use of phosphate rock requires the removal of impurities, a process specific to the grade of the deposit. Mined phosphate rock is washed, crushed, screened, and floated before chemical processing can take place. Beneficiation steps may include separation of particles, crushing, and grinding to separate the phosphate from other material.
