2025-03-20 Experimental data set of niobium extraction by ammonium sulfate enhanced sulfuric acid roasting-fluorine salt leaching process doi:10.57760/sciencedb.22434 en he Bayan Obo rare earth tailings were treated by pickling, and then the tailings structure was destroyed by sulfuric acid-ammonium sulfate roasting, so that the niobium element existing in the dense ore particles was exposed. Finally, the niobium ion was complexed by fluoride salt solution, so that the niobium ion group was stably present in the solution.There are 56 sets of data in this data set.
