There are very few posts in the compound fertilizer section discussing nitrate phosphate fertilizers; after checking, there are only a dozen or so of them, which is rather scarce. It can be said that phosphoric acid fertilizer enjoys strong development prospects abroad, its production technology is well-established, and it is a bulk fertilizer product with significant market potential and competitiveness. In China, the enlargement and localization of such equipment have also been achieved. Research institutions include the South China Chemical Research Institute and the Shanghai Chemical Industry Research Institute, while manufacturers include Tianji Group, Kaifeng Fertilizer Factory, Jinan Fertilizer Factory, etc. These products hold a significant position in the market. But for some reason, its development in the domestic market has stalled, hindering its progress. I would like to ask those who work in the field of nitrate phosphate fertilizers to share their experiences: what problems have they encountered during their work and what solutions did they adopt? This will facilitate communication and learning among us, thereby contributing to the development of nitrate phosphate fertilizer production in our country. After decades of production, the grade of domestic phosphate mines has gradually declined, affecting the quality of the products. How are various companies addressing the issue of declining phosphate rock quality? What impact does this have on product quality? Please discuss.

Reply to 2# tjscyxb: I’m as interested in this as you are; it’s a pity that no one is providing information on this topic. Is this industry kept so secret? It’s a shame I’m an outsider; otherwise I could also act as a moderator
Phosphoric acid nitrogen fertilizer is primarily composed of phosphoric acid and nitrogen, containing about 30% nitrogen and about 6% phosphorus.
Phosphoric acid nitrogen fertilizer is primarily composed of phosphoric acid and nitrogen, containing about 30% nitrogen and about 6% phosphorus.
The phosphoric acid fertilizer we have here contains about 27% nitrogen and about 13% phosphorus.
Currently, the grade of phosphate ores is decreasing, and their impurity composition is becoming more complex. The cost of thermal phosphoric acid is rising steadily, while wet-process phosphoric acid production faces the problem of phosphogypsum pollution. There is an urgent need to find key solutions to these issues
Currently, the quality of phosphate rocks is deteriorating increasingly, with the levels of impurities such as acid-insoluble substances and magnesium oxide rising. This not only causes severe wear on pipeline equipment but also leads to a decrease in nutrients. The top priority is to remove impurities and improve product quality. Who has a good method?
There must be a difference between phosphoric acid nitrogen fertilizers and binary or ternary nitro compound fertilizers, right?
Reply to 9# Li Canghai: There must still be a difference between phosphate nitrate fertilizers and binary or ternary nitro compound fertilizers! Yes, phosphoric acid nitrogen fertilizer belongs to binary compound fertilizers, which are formed through chemical reactions ; Binary and ternary nitro compound fertilizers should properly be called mixed fertilizers or blended fertilizers; the production process is simple – several raw materials are simply mixed together, and it involves mainly physical processes.
What are the consumption figures for phosphatic nitrates, and what about nitrate-based compound fertilizers? Has anyone shared it? I’d like to learn *it*
