<p>The present invention relates to a nickel hydrometallurgical method, and a nickel hydrometallurgical device. The present invention provides the nickel hydrometallurgical method comprising: a leaching step of obtaining a leaching solution containing a nickel ion by leaching nickel from a nickel-containing ore using acid; a leach liquor collecting step of separately collecting solid residues, and a leach liquor containing a nickel ion by centrifugally separating the leaching solution; a depositions step of obtaining a deposition solution containing ferronickel deposits by inputting a nickel-containing ore into the leach liquor containing the nickel ion, and depositing nickel from the nickel-containing ore; and a ferronickel deposit collecting step of separately collecting solid ferronickel deposits and a remaining liquid by separating solid residues from the leach liquor. In addition, the present invention provides the nickel hydrometallurgical device including a leaching tank wherein a leaching action leaching the nickel ion by dissolving the nickel-containing ore is produced, discharging the leach solution obtained by the leaching reaction; a centrifugal separator separately collecting the leach liquor containing the nickel ion and the solid residues by centrifugally separating the leaching solution; and a deposition bath wherein the leach liquor and nickel-containing ore are supplied, and a depositing reaction which the nickel ion of the leach liquor is deposited on the nickel-containing ore is produced, discharging the deposition solution containing the ferronickel deposits obtained by the depositing reaction.</p> |
