| titleOfInvention | Method for recovering metals in laterite-nickel ore leaching solution and producing magnesium salt by resin adsorption method |
| abstract | The invention discloses a method for recovering metals in a laterite-nickel ore leaching solution and producing magnesium salts by a resin adsorption method, which comprises the following steps: adsorbing and resolving the laterite-nickel ore leaching solution subjected to iron precipitation by using first ion exchange resin to obtain adsorbed liquid, and sequentially adjusting the pH of the adsorbed liquid, naturally cooling, and cooling with chilled water to obtain a precipitated magnesium salt and a magnesium-extracted liquid; and adsorbing and resolving the magnesium-extracted solution by using a second ion exchange resin to obtain a mixed solution containing nickel, cobalt and manganese. The method can selectively adsorb nickel, cobalt and manganese from the laterite-nickel ore leaching solution and produce magnesium salts, thereby realizing the separation and recovery of nickel, cobalt, manganese and magnesium and shortening the process flow; the ion exchange resin has long service life and low regeneration cost, thereby reducing the production cost; the obtained nickel, cobalt and manganese have high purity, can be used for producing other downstream products, and has high added value and obvious economic benefit. |
