Leaching characteristics and mechanism of the synthetic calcium-aluminate slags for alumina recovery
(Journal article; Peer reviewed, 2019)The leaching characteristics and mechanism of synthetic CaO-Al2O3 slags in alkaline solution at atmospheric pressure have been studied. The purpose of the study is to have a better understanding of the leaching part of the ... -
Leaching kinetics and mechanism of slag produced from smelting-reduction of bauxite for alumina recovery
(Peer reviewed; Journal article, 2020)In the present study, we investigate the kinetics and mechanism of the leaching of calcium aluminate slag in Na2CO3 solution for alumina recovery. The slag consists of leachable phases, e.g., 12CaO·7Al2O3, CaO·Al2O3, ... -
Recovery of molybdenum and rhenium in scrub liquors of fumes and dusts from roasting molybdenite concentrates
(Peer reviewed; Journal article, 2019)The present work addresses the recovery of rhenium from scrub liquor of molybdenite concentrate roasting fume and dust by solvent extraction method. According to the results, recovery of rhenium from the scrub liquor is ... -
The leachability of a ternary CaO-Al2O3-SiO2 slag produced from smelting-reduction of low-grade bauxite for alumina recovery
(Journal article; Peer reviewed, 2019)A combination of smelting-reduction of bauxite and leaching treatment of the produced slag for alumina recovery is known as the Pedersen process. The process is considered to be more sustainable for producing metallurgical-grade ...
