Selective precipitation of ammonium hexachloropalladate from leaching solutions of cemented palladium with zinc [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 Palladium (Pd) present in spent electroplating solutions is concentrated by cementation with zinc (Zn) metal powder. Therefore, it is necessary to recover Pd from the cemented Pd.

LEACH-G: an Optimal Cluster-heads Selection Algorithm based on LEACH
Journal of Software, 2013 A s a classic clustering algorithm , LEACH is widely used in wireless sensor networks. Due to the random cluster head selection process, LEACH does not guarantee optimization for the number and position of cluster heads . In order to further optimize LEACH, a n optimal energy-efficient cluster-heads selection algorithm LEACH-G for LEACH

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