摘要
In a hydrometallurgical plant of a nickel laterite ore having a plurality of lines of treatment facilities, the hydrometallurgical plant of the nickel laterite ore which is, even when a serious trouble will occur in said treatment facilities, capable of minimizing decrease in throughput caused by this, and restoring a normal operation state early, after eliminating the serious trouble, and an operation method thereof. A hydrometallurgical plant of a nickel laterite ore having a plurality of lines, as treatment facilities including a pretreatment step, a leaching step, a solid-liquid separation step, a neutralization step, a zinc removal step, a sulfurization step and a detoxification step as one line, wherein a coupling pipeline having a valve is installed between a liquid sending pipeline from the solid-liquid separation step to the neutralization step in each line and/or between a liquid sending pipeline from the sulfurization step to the detoxification step in each line.
