In this review, resources of nickel and status of different processes/technologies in vogue or
being developed for extraction of nickel and associated metals from both primary and …

Energy-efficient metal recovery and separation processes from a mixture of valuable metals
are vital to the metallurgy and recycling industries. Oxalate has been identified as a …

The research focuses on extracting nickel and other valuable elements through oxidative
bioleaching from two distinct arsenic-rich ores of varying grades. This process involved …

Indirect bioleaching of Co and Ni from iron rich laterite ore was studied, using spent media
produced by four fungal and bacterial species including Pseudomonas putida …

The bio-dissolution possibility of tungsten from a low-grade scheelite bearing Hutti goldmine
overburden sample was evaluated using two indigenous microorganisms and the results …

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 …

We tested for the first time the efficiency of SiO 2-, Cu-, and Ni-supported Au in deep glycerol
oxidation in a diluted and viscous H 2 O 2/H 2 O liquid phase. Acetic acid (AA), the C 2 …

Nickel production is a very important activity for the European Union because nickel is a
unique constituent of stainless steel. Europe has lateritic (oxidic) ore deposits along a very …

The kinetics of leaching of a Chinese laterite containing maghemite and magnetite in sulfuric
acid solutions was studied in a batch autoclave at temperatures ranging from 230 to 270° C …

Interest in low-grade Ni-laterite ores has increased in recent years; however, the laterite
process has proven technically difficult and costly, and the development of alternative low …
