Limonitic Laterite Ore as a Catalyst for the Dry Reforming

Transmission electron microscopy with energy-dispersive X-ray spectroscopy revealed that Ni existed quite finely in the LN ore but existed as a larger particle (20 nm) in the Ni-supported NN ore. Smaller Ni particles have a higher surface area, resulting in the higher catalytic performance of the LN ore. More CO 2 and CH 4 reacted and higher amounts of H 2 and CO were produced with the LN ore

But they're also low grade, with limonite-type laterite deposits containing around 1%-2% Ni and saprolite-type ore a little more, up to 2.5% Ni-and they have other specific characteristics that make acceptable rates of metal recovery a difficult proposition. Nevertheless, they are estimated to contain more than 70% of the world's known nickel resources and are a tantalizing target for

Limonite - Wikipedia

Limonite usually forms from the hydration of hematite and magnetite, from the oxidation and hydration of iron rich sulfide minerals, and chemical weathering of other iron rich minerals such as olivine, pyroxene, amphibole, and biotite. It is often the major iron component in lateritic soils.

The high pressure acid leach process (HPAL) is being commercially used in four plants around the world to treat . limonitic laterites. The two major operating costs of the HPAL process are the sulphuric acid and the energy required to heat the pulp to the desired temperature (>240°C). As an alternative to acid injection and steam heating, the in-situ generation of sulphuric acid and heat

Processing of Nickel Laterite Ores on the Rise

Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits. Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are more amenable to processing via pyrometallurgy.¹

The E Extraction from Limonite Ore by Using 2-Air

This process is carried out at atmospheric pressure and is shown to have good selectivity of nickel over iron, but with a low recovery yield. The literature refers to the application of alkali roasting as pretreatment in laterite ore leaching to increase nickel recovery. Thus, this study aims to apply the combination method of alkali roasting and leaching to extract nickel from limonite ore (1
