  • Phosphorite - Wikipedia

    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 5.This occurs through washing, screening ...

  • Phosphate - Wikipedia

    Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H

  • Understanding phosphorus fertilizers | UMN Extension

    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 ...

  • Phosphate: A Critical Resource Misused and Now Running

    Jul 07, 2011 · The world’s food supplies are alarmingly dependent on the phosphate fertilizer that is hewn from the desert of the Western Sahara. The vast open-cast mine at Bou Craa delivers several million tons of phosphate rock every year down a 150-kilometer-long conveyor belt, the world’s longest, to the Atlantic port of El Ayoun.

  • Organic Fertilizer Manufacturer - Phosphate Fertilizer

    Phosphate is a major nutrient that promotes overall plant cell health, tissue growth and better yielding crops. Fertoz aims to offer a quality organic fertilization option that is natural, high in available phosphorus (the sum of the phosphorus soluble in water plus that which is soluble in a citrate solution), and free of contaminants.

  • Diammonium Phosphate | Mosaic Crop Nutrition

    The inputs required to produce one ton of DAP fertilizer are approximately 1.5 to 2 tons of phosphate rock, 0.4 tons of sulfur (S) to dissolve the rock, and 0.2 tons of ammonia. Changes in the supply or price of any of these inputs will impact DAP prices and availability.

  • Single Superphosphate (SSP) | Impact Fertilisers

    Single Superphosphate is produced by reacting naturally occurring phosphate rock with sulphuric acid. This process converts insoluble phosphates into forms more readily available to plants. Phosphate Rock + Sulphuric Acid → Single Superphosphate. Impact Fertilisers’ SSP manufacturing process uses blends of various rock phosphate rock sources.
