Extraction of metals from saprolitic laterite ore through pressure hydrochloric-acid selective leaching [PDF]
In this study, pressure hydrochloric-add selective leaching was used to leach Ni and Co from saprolitic laterite ore on the basis of potential-pH diagrams constructed for Fe-Si-Cl-H2O and Ni-Si-Cl-H2O systems. The leaching of Ni, Co, Mg, Mn, and Fe was

Selective precipitation of ammonium hexachloropalladate from leaching solutions of cemented palladium with zinc [PDF]
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
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
