Microbial leaching of copper with the common copper ore CuS, in which copper exists as Cu2+   Acidophillus ferrooxidans oxidizes the sulfide in CuS to SO42, releasing Cu2+.

In uranium leaching, Acidophillus ferrooxidans oxidizes U4+ to U6+ with O2 as an electron acceptor. 

However, Uranium leaching depends more on the abiotic oxidation of U4+  by Fe3+ with A. ferrooxidans contributing to the process mainly through the reoxidation of Fe2+ to Fe+3, as in copper leaching.

The major form of Hg in the atmosphere is elemental mercury (Hg0 ), which is volatile and is oxidized to mercuric ion (Hg2+) photochemically. Most mercury thus enters aquatic environments as Hg2+.
