Why is Filter Aid Used in The Fertilizer Industry?

Introduce phosphate mining process. For high quality fertilizer to be applied in the fields, the entire supply chain, from the mines, to granulation, to transportation and retailing, must maintain high efficiency and performance. Phosphate rock is mined. It undergoes a beneficiation process. Mention the flotation process. NAQ global has a range of flotation products. The product range NAQ FLOAT yields a high phosphate recovery and selectivity. Although some products offer only high recovery, the selectivity is equally important. Depending on the flotation process, the forward or reverse process, the amount of gangue materials in the targeted compound should be diminished. From mining products, to granulation, and to transport and retail, NAQ offers complete solution for fertilizer quality improvement.

Phosphate rock is then used to make phosphoric acid by reacting the rock with sulphuric acid. The resulting slurry undergoes a filtration process to separate the phosphoric acid from the gypsum. This filtration step is vital for achieving high phosphoric acid recovery and purity. Since phosphoric acid is a highly valuable commodity, every small increment in the yield of P2O5 is highly important. NAQ Global offers specialized filtration aid for phosphoric acid plants designed to enhance this crucial phase of phosphoric acid production. NAQ Global offers a wide range of filtration aids, crystal habit modifiers, and flocculants for all fertilizer industry applications. The main advantages of using these high performance chemicals are as follows:

Better water clarity and quality, with limited BOD and COD

Environmental compliance for clean water discharge

Efficient use of water for the mineral handling process

Conclusion

The most prevalent and valuable types of phosphate fertilizers use phosphoric acid as the key raw material. High quality phosphoric acid eventually leads to better quality of fertilizer in the processes following the phosphoric acid production.
