US6261527B1 - Atmospheric leach process for the recovery of .A number of new hydrometallurgical processes are being developed for the extraction of nickel and cobalt from nickeliferous laterite ores. Many of these processes require the dissolution of the metal values with sulfuric acid at high temperature (245°-270° C.) and pressure (525-785 psig), followed by solid-liquid separation.A Study on Classification of Limonite and Saprolite from Nickel .Nov 24, 2017 . It is therefore required that separation of saprilite-type ore to use nickel laterite ore as a raw material for hydrometallurgy process. In this study, separation of sparolite-type ore and limonite-type ore from nickel laterite ore from New Caledonia has been tried by dry classification. The results show that -5 mm.
Nickel processing | BritannicaBecause some nickel-bearing sulfides are magnetic, magnetic separators can be used in place of, or in conjunction with, flotation. . Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect.saprolite ore separator,gravity separation of nickel laterite oreAug 10, 2016 .
