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 …

With the growth of the stainless-steel industry, the focus has moved toward making
specialized steels, where Ni has proved itself as a significant ingredient. With time, Ni …

In our previous study, the mineral evolution and porous kinetics during nitric acid pressure
leaching of limonitic laterite has been investigated. In order to optimize the nitric acid …

During the recent years, selective leaching from laterite ore has gained considerable interest
from the scientific community because of the growing demand of valuable metals including …

Cobaltite (CoAsS) is a strategically important mineral. This work investigated the bioleaching
of cobaltite-bearing magnetite-rich ore. The bioleaching of cobaltite was carried out with …

Socio-economic data on nickel and cobalt show their importance throughout the entire metal
value chain, from mining to end use, disposal and recycling. Thus, the extraction of both …

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 …

Following the growing demand for Ni and Co and the dwindling supplies of sulfide nickel
ore, attention has turned toward the more efficient exploitation and utilization of laterite ore …

This study investigated the effect of activation pretreatment of limonitic laterite ores using
sodium fluoride and sulfuric acid on water leaching of nickel (Ni) and cobalt (Co) over iron at …

The effect of pre-roasting on the atmospheric sulfuric acid leaching behavior of saprolitic
laterites, obtained from Indonesia, was investigated. The phase transformation of laterite …
