    摘要: A porous tin particle and its preparation method are provided in the present invention. The method includes steps of: (a) performing a reductive (or reductive electrochemical) reaction on a tin particle which simultaneously reacts with lithium ions to form a tin-lithium (Sn—Li) alloy; and (b) performing an oxidative (or oxidative electrochemical) reaction on Sn—Li alloy to release the lithium ions therefrom, and the porous tin particle is formed. The porous tin particle could be further applied in manufacturing the electrochemical electrode for lithium-ion battery with longer cycle life and higher reversibility.

    摘要: A process for extracting precious metals form ore that includes: collecting the ore, crushing the ore, enriching the ore using sulphuric acid at least in one washing cycle. Then precious metals are leached from the enriched ore by a non-aqueous solvent containing brome or bromide. The ore is than press filtered and direct electrical current is applied to the solvent bearing the precious metal, following which the metal is collected from the anode.
