Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops. Many of the mines that produced rock phosphate are closed, and most of the marketed rock ...

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.

Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs ... Aug 12, 2019 Studies done on leaching from rock phosphate compared to conventional fertilizers and found very high losses of phosphorus from conventional fertilizer. 96.6 percent of conventional phosphorus applied as fertilizer was leached, while only 0.3 to 3.8% was leached from rock phosphate fertilizer.

Jan 25, 2016 Uranium is a naturally occurring radioactive element present in phosphate rocks, usually present as U 6 in the apatite minerals phase in the Jordan phosphate rocks (Al-Hwaiti 2000). The mean of U concentrations of phosphatic- A 1 mine waste water and phosphatic- A 3 mine waste water are 5.6 0.2 and 5.5 0.3 g/L, respectively (Table 6 ). of P2O5 in Jordan the ratio is around 5.0 5.3 ton of PG / ton of P2O5 produced depending on the phosphate rock composition, which means a huge amount of PG will accumulate at the Fertilizer plant in Aqaba. The major advantages of using orthophosphoric acid as leaching solvent is the decreasing ratio of the residual materials verses

It is well known that the phosphate deposits exhibit variable enrichments in certain major, minor and trace elements worldwide (Plank Langmuir, 1998). Dec 13, 2016 Rock phosphate is found in all continents of the world (figure 1). It is used as a raw material in the manufacture of inorganic phosphorus fertilizers and can be used as organic phosphorus fertilizers when applied directly to the soil. Direct application of rock phosphate increases crop yield and soil phosphorus levels (1, 2,3).

*In the trade the phosphate content of phosphate rock and fertilizer is commonly re ported as Ca3(PO4 2, known as bone phosphate of lime (B.P.L.). To convert PjOs to B.P.L., multiply percentage P2Os by 2.18. To convert to P, multiply percentage P2Os by 0.436. In 2013 we started trading of rock phosphate from Egypt and Jordan, and we are in a position to supply any quantity as we have our mining company in Egypt and Sudan. We trade fertilizers like urea from Egypt, SOP and TSP from Jordan, and sulphur from Tupras, Turkey
