PLANT FOR WET SMELTING OF LATERITE NICKEL ORE AND METHOD OF OPERATING SAME

摘要

Disclosed is a plant for wet smelting of laterite nickel ore which can minimize stops of a processing facility even in the event of a serious trouble in the processing facility, the processing facility requiring a great deal of preparation time for a setup or shutdown when recovering from the serious trouble. The plant (20) for wet smelting of laterite nickel ore may have two or more lines of a series of processing facilities, each line including in-line processing facilities, a utility supply facility (8a, 8b), a hydrogen sulfide supply facility (10a, 10b), a flocculant supply facility (14a, 14b), and a neutralizer supply facility (12a, 12b). In the plant (20), the utility supply facilities (8a and 8b), the hydrogen sulfide supply facilities (10a and 10b), the flocculant supply facilities (14a and 14b), and the neutralizer supply facilities (12a and 12b) in the respective lines each further include a link facility for linking to each other to enable the utility, hydrogen sulfide, flocculant, and neutralizer to be shared therebetween.
