摘要： Provided are a method for processing a laterite-nickel ore and a method for recycling scandium. The method for recycling scandium includes steps of: extracting scandium from scandium-containing leachate with an organic extractant, so as to obtain a scandium-containing organic phase; subjecting the scandium-containing organic phase to back-extraction with a monovalent acid, so as to obtain a strip liquor; mixing the strip liquor with a precipitant, so as to obtain a scandium-containing precipitate; and calcining the candium-contained precipitant, so as to obtain scandium oxide.
