Polymetal

Primarily used in chemistry or mining, polymetal or polymetallic refers to a substance comprised of a combination of different metals. When the substance contains only two metals the term "bimetal" ("bimetallic") is sometimes preferred (not to be confused with "bimetallism", which refers to a type of monetary system).

* A polymetallic ore (or "polymetal" ore) is an ore that is the source of more than one metal suitable for recovery.
* A mine containing polymetallic ore is a polymetallic mine.
* Polymetallic nodules are concretions of manganese and iron (and other metals) found on the ocean floor. They are sometimes called "manganese nodules", after their principal component.
