Leaching kinetics and mechanism of slag produced from

2020-8-1 · In the present study, we investigate the kinetics and mechanism of the leaching of calcium aluminate slag in Na 2 CO 3 solution for alumina recovery. The slag consists of leachable phases, e.g., 12CaO·7Al 2 O 3, CaO·Al 2 O 3, 5CaO·3Al 2 O 3, and a non-leachable phase that contains Ca-Al-Si-Ti oxides.A series of leaching treatment is done at different temperatures, leaching times, stirring

The Leachability of Calcium Aluminate Phases in Slags for

It is apparent that the leachability of a phase affects that of other phases. A less leachable phase could hinder the leachability of a more leachable phase. The experimental data shows that the leaching rate of slag from highest to the lowest is CaO.Al2O3, 3CaO.Al2O3, and CaO.2Al2O3, respectively.
