Who knows what’s wrong with Yuntianhua’s diammonium phosphate?
Thread Content
I heard that before the festival, Honglin Company, which is part of Yuntianhua International, faced a situation where the phosphorus content in the ore was insufficient, preventing it from producing 64% diammonium phosphate; meanwhile, Cargill was also unable to produce it； I heard after the holiday that Cargill has resumed operations, but Sanyuan Sinochem is also facing this problem. What’s the exact situation? Does anyone know more details? Normally, Phosphating Group should still have high-quality phosphate mines available, and since they have flotation equipment, they shouldn’t encounter such issues!
Industry problems: the mines are getting worse and there are many issues
It seems that the production of blended fertilizers will be affected
I’m from Sanchuan Sinochem. The ore quality of ours is too poor; the concentration of dilute acid is low, and there are many impurities
Brothers upstairs: Is the phosphate rock you’re using currently being cleaned by scrubbing or flotation? Can it still reach over 29% phosphorus pentoxide? I met an engineer from a foreign company, who said that in your phosphating company’s flotation process, one additional step is needed in order to increase the grade of the concentrate; however, this also increases the costs.
If this is the case for all phosphate deposits, it becomes even more difficult to ensure quality, as the grade can drop to 27-28%, meaning the impurities are naturally high! The quality of phosphate rocks is getting worse and worse these days, making production very difficult.
I wonder how much longer phosphorus fertilizer raw materials will be available, and whether we will end up relying heavily on imports for them just like with potassium fertilizers
The ore we use for flotation has a grade of around 27% at present; it’s difficult to process due to the high magnesium oxide content
Given the severe decline in the quality of phosphate mines, high levels of impurities in phosphoric acid, nutrient contents sometimes falling below 64%, low strength of the products, and excessive dust at the production sites, what measures are being taken to address these issues? :L
I think new technological innovations or a modest reduction in industry standards for nutrients could be considered; otherwise, we cannot face reality. This is a major challenge in phosphating production across the country at present.
If the nutrient content is below 64% (especially phosphorus pentoxide below 46%), there will be problems with export, as this is the international standard. The phosphating group should be able to carry out double flotation.
