• Extracting a metal from its ore

    Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

    Obviously, coextracted metals with U(VI) by tertiary amine are Mo(VI), Zr(IV) and V(V) especially at higher pH such as 2. Mo(VI) extraction with tertiary amine is stronger than that of U(VI) within the extraction pH range of as shown in Fig. 6. For vanadium, only V(V) can be extracted by tertiary amine at a relatively high pH such as 2.
