Study on factors affecting rare earth leaching rate in acid leaching process of fly ash
View through CrossRef
There is a large amount of enrichment of rare earth elements in Zhungeer coal and coal ash, making it possible to use fly ash as a source for industrial production of rare earth elements. In order to optimize the leaching process of rare earth elements in fly ash and increase the leaching rate, the circulating fluidized bed fly ash of Zhungeer Power Plant was used as the material, and the single factor test and orthogonal test were used to influence the leaching rate of rare earth elements in the acid leaching process of fly ash The factors were discussed, and the results showed that when fly ash and 3mol/L hydrochloric acid were leached at a ratio of 1:10 for 2h at 130 0C, the element leaching effect was the best, and the leaching rate could reach 97%.
