Use of biological organisms, such as, bacteria, fungi (usually), and plants to reduce or eliminate toxic pollutants from contaminated sites by degradation or assimilation in the atmosphere is called bioremediation.

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+.
