Nickel is a strategic element whose production and consumption in over a decade has
increased to over 39% and 71%, respectively. Generally, due to their complex mineralogy …

The challenges in processing nickel laterite ores using flotation process were
comprehensively reviewed. Literature shows that flotation has not been successful to …

Deterioration of mineralogical and physical characteristics of mineral raw materials results in
the formation of the primary task for the comminution processes—reduction in the size of ore …

In this study, experimental data for wet-and dry-ground coal samples under wet and dry
grinding are characterized by commonly used distribution functions. First, both the RR and …

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 …

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

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 …

The mining energy value chain starts at the face and extends to smelting and refining.
System designs that conserve energy and apply energy-efficient technologies can result in …

The objective of this study is to establish a mathematical model to evaluate the unequal-
probability comminution of minerals during the grinding process. The effect of the grinding …

In this study, the Taguchi method was used to study the influence of feed size, ball diameter,
pulp density and grinding time on the grinding performance of wet ball-milling. According to …
