The kinetics study on alumina leaching from calcined Akpugo kaolinite was considered in
this study. The shrinking core model and other relevant kinetic models were used for kinetic …

In this study, the effectiveness of hydrochloric acid and hydrogen peroxide binary solution as
lixiviant for alumina recovery from Owhe kaolinite is investigated by kinetic and optimization …

The leaching of alumina from Amagunze microcline in nitric acid/hydrogen peroxide binary
solution was examined in this study. The parameters considered in the study include …

Recovery of alumina from kaolinite presents a sustainable alternative to its recovery from
bauxite, a major source of alumina which is depleting in quantity globally. Owhe kaolinite …

In this research, some physical properties such as the density, specific heat capacity, and
micro-hardness of galena ore lumps purchased from the public market were determined …

In this work, the kinetics of alumina recovery from Akpugo kaolinite in nitric acid and
hydrogen peroxide binary solution are investigated. Parameters considered in the study …

Galena is a natural mineral enriched with lead sulfide (PbS). It typically forms in
hydrothermal veins associated with igneous rocks and can also occur as a gangue mineral …

Lead sulfide (PbS) on the nanoscale was synthesized via a chemical route at room
temperature using lead nitrate {Pb (NO3) 2} and sodium sulfide (Na2S). The Na2S was …

Investigations on the kinetics of leaching lead from galena (PbS), using acetic acid (HAc)
solutions in iron (III) chloride (FeCl3) solutions, were conducted using shrinking core …

The potential of a Nigerian lead ore in form of galena and anglesite containing 72.82 wt%
Pb, 19.95 wt% S, 3.07 wt% Au and 2.77 wt% As, as major elements was treated by sulfamic …
