Kinetics, as a fundamental requirement of nearly all industrial activities and engineering
researches, plays a great role in leaching processes. Although there are many pieces of …

In this work, vanadium (V) was selectively extracted from fuel-oil fly ash using a leaching
process utilizing organic acids extracted from lemon juice with assistance from ultrasound …

High-temperature ferric leaching is a promising method to improve the recovery of
nonferrous metals from sulfide ores and concentrates. In this study, differences in the …

This work focuses on the open-loop and closed-loop analysis of a continuous stirred tank
reactor for zinc leaching from sphalerite (ZnS) via modeling and simulation approaches. The …

Laterite-nickel ore was roasted with ammonium sulfate to extract magnesium by a single-
factor experiment, and an orthogonal test was employed to optimize the conditions. The …

This study showed the kinetics of gold chlorination leaching from an anode slime complex
containing copper, silver, barium, selenium, and tellurium. AgCl and BaSO 4 control the rate …

The gas-liquid flow and oxygen content in a pressurized leaching stirred tank significantly
influence the chemical reaction rates, while the specific dynamics of gas-liquid flow in the …

Because the traditional roasting-leaching-electrowinning zinc hydrometallurgy process has
a small sulfuric acid sales radius and a high inventory pressure, the process of direct …

Dissolution of a Nigerian antigorite-rich dolomite ore in methanesulfonic acid (MSA) solution
for its optimal industrial application was investigated. The impact of the acid concentration …

ABSTRACT A vertical tubular reactor is used for the oxidative leaching process in the
mineral processing industry, especially sphalerite. Oxygen could oxidise ferrous ions (Fe2+) …
