Abstract
Ab ract. The processes of extraction of cerium and neodymium from Kazakh an phosphogypsum, a large-tonnage wa e of mineral fertilizer production of “Kazphosphate” LLP, have been udied. The elemental analysis was udied. It has been found that the use of hydrogen peroxide as an oxidizer in the and by 28% for neodymium. Optimal parameters of cerium and neodymium leaching under atmospheric and autoclave conditions have been found. In atmospheric conditions, recovery of cerium and neodymium were 70.3% and 92.0%, in autoclave conditions 72.9% and 87.5%, respectively. The obtained results allow us to hope for the processing possibility of these wa es with the aim of rare-earth metals and other valuable products recovery.
Ab ract。研究了从哈萨克斯坦磷石膏中提取铈和钕的工艺。进行了元素分析。已经发现，使用过氧化氢作为氧化剂在钕中可减少28%。研究了常压和高压釜条件下铈、钕浸出的最佳工艺参数。在常压条件下，铈和钕的回收率分别为70.3%和92.0%，在高压釜条件下分别为72.9%和87.5%。所获得的结果使我们对这些金属的加工可能性抱有希望，目的是回收稀土金属和其他有价值的产品。
