With the depletion of sulfide nickel mineral resources and rising demand for nickel, extraction of valuable metals such as Ni and Co from nickel laterite ores have been paid greater attention although such ores have lower grades (0.75–3%) and are more difficult to treat compared with sulfide nickel ores (Oxley and Barcza, 2013, Fan and …
Reductive acid leaching of limonite (goethite in particular), resulting in nickel release has been demonstrated in mildly acidic conditions (pH range 1.5–2) at atmospheric pressure and ambient temperature (25–30 °C) using Acidithiobacillus ferrooxidans (Hallberg et al., 2011).The leaching process is based on the reduction of ferric iron contained in …

The mineralogical properties of saprolite and limonite from Indonesia were investigated by X-ray diffraction, X-ray fluorescence, atomic absorption spectro-photometer, field-emission scanning ...
The Caron process is most effective when applied to high goethite limonite ores (De Graff, 1979, Canterford, 1975, Power and Geiger, 1977). Saprolite or silicate-rich laterite minerals tend to undergo phase transformation that results in poor metal recoveries when treated with this process (Kukura et al., 1979, Stevens et al., 1975).
This free acid is around 20–30 g/L in the case of limonite processing, compared to 50–60 g/L in the case of processing of limonite/saprolite blends (Baghalha and Papangelakis, 1998). However, free acid measured by titration at room temperature does not reflect the true concentration of hydrogen ion (or pH) at elevated temperatures, …

The Agata North laterite nickel mineis located along the western range of the Surigao region of Mindanao and has an area of over 340ha. The mine is filled with nickeliferous laterite deposits within the mineralised plateaus along the Western Range. The laterites are believed to have formed due to chemical weathering of t…
The goethite process at a lower pH minimizes the loss of nickel during the precipitation of iron from clarified nickel(II) leach liquors, but generates precipitates of poor filterability. To solve the filtration problem, limonite seeds were applied to induce crystallization and improve the goethite precipitation.
CARON PROCESS • It is not a new process and was first proposed by Professor Caron, Delft University Netherlands, in the 1920s. • It was pioneered commercially by Freeport at Nicaro, Cuba, in 1944, then taken over by the Cuban Government in 1960. It is still in operation. • A further five plants were constructed in the 1970s -1990s,
After reasonable mineral processing equipment configuration and scientific limonite process design, the grade of iron concentrate will be increased by 35% and 40%. After simple smelting, metal iron can be used in industry, and it is widely used including: iron and steel production enterprises, which is the main raw material for steelmaking.
The generic formula is often written as FeO(OH)n. H2O, and limonite is one of the three principal iron ores, the others being hematite and magnetite. In an application of limonite ore, a pyrolysis of lignins has produced high-quality bio-oils containing 55% alkyl phenolics and 27% aromatics, with the use of limonite as catalyst (Hita et al., 2018).
