Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

Morocco (27.0 million metric tons) (Jasinski, 2012). The US is the leading exporter of processed phosphate products, chiefly fertilizer, supplying 25% of the world demand (Jasinski, 2010). The US does not export phosphate rock, but did import 2.5 million metric tons to meet its domestic and foreign demands for fertilizer (Jasinski, 2011).

ICL's subsidiary, ICL Rotem, mines phosphate at Rotem and Zafir (Oron- Zin) in the Negev Desert. The p hosphate rock is processed, in plants located at Mishor Rotem, into fertilizers (phosphorus is a vital plant nutrient), as well as numerous other products used by the food, cosmetics, dental products, detergents, light-emitting diodes (LED) industries and others.

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O …

Phosphate Beneficiation. Market Specifications Bone phosphate of lime, 70 to 72 per cent, common. Bone phosphate of lime 72 to 77 per cent, premium. Production Problems. Phosphate rock being a low-priced material is produced as near the fertilizer market as possible and haulage costs determine production.

In this paper, the beneficiation of rejected phosphate washing sludges (Ps) was investigated using acid leaching methods. Chemical analysis showed that these sludges are a low-grade ore (15.84% P2O5). The optimum milling parameters have helped to increase the P2O5 grade to 18.51%. Then, the effects of three different organic acids (acetic, lactic, and citric acid), acid …

In Morocco, huge piles of phosphate waste rock and tailing ponds that cover thousands of hectares, with very limited vegetation and subjected to wind and water erosion, not only spoil the landscape but are also a serious source of pollution (Hakkou et al., 2016). Revegetation of phosphate mine wastes has therefore become a national priority for ...

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.

Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate).

This implies that the proportion of rock-type in the studied mixtures is reversibly proportional to its nutrient content in acid solution. As such example, citrate-soluble phosphorous is extracted at 17.16% total solubility when the proportion of phosphate rock is twice at phosphate-rich M#2, whereas it is recovered at 25% in shale-rich M#4.
