process recovery besi from laterite

Recovery of metals by ion exchange process using chelating Chelating ion exchange resins can be used to recover metals from nickel laterite leach solution. The main problem is the high presence of iron. In pH above 2.00, iron precipitates and there is co-precipitation of copper and cobalt, which decreases recovery process efficiency.

01.05.2010  High pressure acid leaching is the main process for industrial production of nickel and cobalt with lateritic ore, but it is applicable only for limonite (high iron laterite) in order to minimize acid consumption. Another disadvantage of this process is that it requires expensive autoclaves and also needs high maintenance costs. Recently, interest has been created to

Laterite ore is one of the important sources of nickel (Ni). However, it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate (Na2S2O3) as a promoter. . It was found that a Ni content of 9.97% and a Ni recovery of 99.24% were
