Abstract Perchlorate (ClO 4−) is a strong oxidizer and has gained significant attention due to
its reactivity, occurrence, and persistence in surface water, groundwater, soil and food …

The dissolution behaviour of a series of d-and p-block metal oxides was investigated in
deep eutectic solvents, DES, to determine the effect of pH and hydrogen bond donor (HBD) …

Water treatment with metallic iron (Fe0) is still based on the premise that Fe0 is a reducing
agent. An alternative concept stipulates that contaminants are removed by adsorption, co …

Iron-rich, limonitic laterites may contain economic grades of nickel and cobalt, but efficient
extraction of these metals from such ores is still a challenge. In this study, four samples of …

Atmospheric acid leaching behaviour of scandium (Sc) in two different types of laterite nickel
ore from Indonesia was investigated. Ore and leaching residue characterization was …

Improved atmospheric acid leaching (AL) of complex, low grade nickel (Ni) laterite ores
warrants greater knowledge of the exact processes underpinning Ni and pay metal cobalt …

The reductive leaching behaviour of manganese (Mn) and cobalt (Co) in a laterite and a
pure manganese ore was investigated by varying and optimising various leaching …

Based on the advantages of nitric acid pressure process (NAPL) for laterite nickel ores, this
study innovatively proposes nitric acid pressure leach liquor crystallization pyrolysis-mixed …

Substance flow analysis (SFA), an analytical tool, was applied to a high-pressure acid
leaching (HPAL) process of laterites. The results show that although the HPAL process has …

Nickel, cobalt and iron were extracted from Caldag lateritic nickel ore under atmospheric
pressure acidic leaching conditions. The following variables were examined to understand …
