In this study, the leaching behaviour of zinc from a smithsonite ore sample (23.43% Zn)
having goethite and calcite as main gangue minerals was investigated in sodium hydroxide …

Clay is widely used in a number of industries due to its special properties like fine particle
size, brightness and whiteness, chemical inertness, platy structure, etc. In this study, the …

In the present study, the production process of zinc sulfate from the zinc oxide ore was
experimentally investigated. The effect of main operating condition such as weight ratio of …

The effects of leaching temperature (60− 105° C), NH 4 Cl concentration (3− 7 mol/L),
liquid/solid ratio (4: 1− 12: 1 mL/g), stirring speed (150− 750 r/min), and leaching time (5− 90 …

This study investigated the kinetics of copper leaching from malachite ore using formic acid
as an organic leaching reagent. The analysis was carried out to determine the effect of the …

With advancements in hardware and software, non-destructive radiometric analytical
methods have become popular in a wide range of applications. A typical case is the study of …
