Beschreibung
Zusammenfassung:	The invention provides a treatment method of laterite-nickel ore acid leaching residues and an active material. The method comprises the following steps that S1, the laterite-nickel ore acid leaching residues, an adjusting material, a fluxing material and a reducing agent are mixed and pressed, and a prefabricated product is obtained; s2, roasting the prefabricated product to obtain hot cinder and hot flue gas, and using the hot flue gas to prepare acid; s3, magnetic separation is carried out on the hot cinder, and a refined iron material and tailings are obtained; and S4, mixing the tailings, the active material and the excitation material, and grinding to obtain the active material. The treatment method disclosed by the invention has the characteristics of large solid waste consumption, multiple types of generated products, high product output value, low comprehensive production cost, high resource utilization rate and the like, and provides a more effective solution way for full recovery of valuable compon
