Problems with the concentration of wet phosphoric acid
Thread Content
Phosphoric acid produced by using phosphate rocks from Sichuan, during the concentration process, reaches a concentration of around 45%; at this point, impurities precipitate, resulting in very high viscosity and making it difficult to continue with the concentration process. What are some ways to solve this problem?
Is this question difficult? No one on the forum could answer it?
At the moment, there is no good solution; the only option is to remove impurities from the phosphate ore
