Copper and cobalt can be found on nickel laterite ores, and cobalt can be found also on
copper ores, and many contaminants such as iron, aluminum, and magnesium are …

The global movement toward the pillars of a circular economy has restructured the entire
chain of the primary production sector. Together, increases in the consumption of critical …

In this study, an alternative method for recovering nickel and other valuable metals from
nickel laterite ores is proposed and evaluated. The proposed method comprises a leaching …

Ammonium sulfate roasting-water leaching technology is a potential cleaner production
process with low energy consumption, minor equipment corrosion and high selectivity …

Each year a tremendous volume of V-Ni rich ashes is produced by fuel oil consuming power
plants throughout the world. Recovery of precious metals existing in these ashes is very …

The waste product from the hydrometallurgical processing of nickel laterite ores can contain
valuable metals, making their recovery economically viable. However, the high‐impurities …

Nickel plays a critical role in the mining industry. However, the presence of nickel in the
primary source of sulfide minerals is decreasing. Focus has since turned to laterite ore …

Nitric acid pressure leaching (NAPL) of limonitic laterite is a recently developed technology
by our group, which is in line with the concept of clean and sustainable development for the …

More than 70% of the world's nickel reserves are found in laterite ores. In this research, a
laterite ore sample, containing Ni, Co, and Fe, was employed to study the recovery of nickel …

The bioleaching efficiency and mechanism of recovery of cobalt (Co) and nickel from
laterites and pyritic ores by Aspergillus niger were investigated. Recoveries of Co from …
