Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
Bone meal fertilizer makes a wonderful organic fertilizer to supply your plants with important nutrients like calcium and phosphorus, promoting strong, healthy plants and produce. However, it may not be suitable for every garden. Be sure to perform a soil test before choosing a fertilizer for your garden. Article Sources.
Here it goes: Wet Process for Phosphoric Acid: Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2 .CaF 2, by the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactors. This results in phosphoric acid and calcium sulfate (gypsum) plus other insoluble impurities.
plant for future use. The rock is slurried in water and wet-ground in ball mills or rod mills at the chemical plant. Consequently, there is no significant emission potential from wet grinding. The small amount of rock that is dried in Florida is dried in direct-fired dryers at about 120°C (250°F), where the
The wet milling machine benefits make them attractive investments. IKA wet milling machines are based on the rotor-stator principle. Exhibiting a high level of shearing energy input, milling machines can achieve particle sizes of 10 µm and below. IKA wet mill machines are capable of processing products with a broad spectrum of viscosity.
With some concentrates these can be varied within certain limits. Pelletization process. A pelletizing plant normally has four process steps namely (i) receipt of raw materials, (ii) pretreatment, (iii) balling, and (iv) induration and cooling. These process steps are described below. Receipt of raw materials.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
Phosphorus is a vital component in the process of plants converting the sun's energy into food, fiber and oil. Phosphorus plays a key role in photosynthesis, the metabolism of sugars, energy storage and transfer, cell division, cell enlargement and transfer of genetic information. Phosphorus promotes healthy root growth, promotes early shoot ...

Inappropriate application of plant nutrients induces 40–70% loss of nutrients and causes contamination of land and water systems. Nano-fertilizers provide nutrients precisely to the plant's requirement, and thus reduces the environmental loss of nutrients. Synthesis of nanoparticles is carried out by either top-down or bottom-up methods.
