摘要： A hydrometallurgical plant for nickel laterite ore extraction having a plurality of treatment facility lines wherein the plant is capable of minimizing a decrease in throughput when line failure occurs and efficiently restoring normal operation status Each line of the treatment facility includes 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. The lines are coupled by pipelines, each having a valve, installed after the solid-liquid separation step for sending a liquid from the solid-liquid separation step to the neutralization step in each line and/or after the sulfurization step for sending a liquid from the sulfurization step to the detoxification step in each line.
