Study of the Mechanochemical Calcification for Mixed Rare Earth Concentrate, the leaching yield of rare earth reached to 92.16%, Ce was 86.47%, La was 97.58%, Nd was 99.99% and the mass fraction of F, P entering into calcified liquor were 8.27, 0.21% respectively. The micromorphology of the mineral has a transition from dense to fluffy, and then became dense again.

Electrochemical Formation of Tb Alloys in Molten LiCl–KCl Eutectic Melts and Separation of Tbined at 1.60 V for 3 h was Ni. Alloy samples were prepared by potentiostatic electrolysis at 0.50–0.80 V for 1 h using Ni plate cathodes in a molten LiCl–KCl containing TbCl. (0.50 mol%) and NdCl. (0.50 mol%). The highest mass ratio of Tb/Nd in the alloy sample was 56 at 0.70 V.

Cyclone Electrowinning of Antimony from Antimonic Gold Concentrate Oresomic profit of CE was 33.1% higher attributed to the high current efficiency of CE. In addition, CE could adapt to high current density. All these characteristics indicate the CE method can be implemented commercially for processing antimonic gold concentrates.

Electrodeposition of γ-MnO2 from Manganese Nodule Leach Liquor: Surface Modification and Electrochem drastically decreased the current efficiency (CE) and increased the energy consumption (EC) during electrodeposition. Under the optimum CTAB concentration of 100 mg dm. the obtained CE and EC values were 87.64% and 1.70 kWh/Kg respectively.
