Attack of the Rock-Eating Microbes!
Some bacteria break down minerals, while others make them

Heavy Metals are elemental not mineral. Breaking down an element requires nuclear forces. You can biochemically combine elements but you are not "breaking them down."
When speaking of heavy metal, geochemists don't usually mean the atoms. Very few heavy metals are ever found in nature as pure elements. They are almost always found combined with other elements in characteristic molecules and minerals. When geochemist say heavy metal, they often mean the characteristic molecule or mineral in which the said metal is usually found. So when chemist say breaking down heavy metal, they don't mean nuclear fission. They mean chemically taking apart the characteristic molecules in which the heavy metals are found.
Organic action changes the chemical environment around heavy metal atoms, and cause them to undertake chemical reaction inside the organism, or outside the organism, that would otherwise never occur or highly unlikely to occur. The change occurs at a chemical level, not nuclear level. Atomic nuclei do not change. Electrons and molecules do, as a result of biological activity.
