Selective leaching of Mo from an off-grade gravity lead concentrate in Na2CO3 solution [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2019
The selective leaching of Mo from an off-grade gravity lead concentrate was investigated in Na2CO3 solution using air as an oxidant. The leaching behaviors of Mo and Pb were predicted by the thermodynamic phase diagrams of Pb-Mo-C-H2O system.
