Why iron pyrites is not considered an ore?

An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. Pyrite is composed of iron and sulfur; however, the mineral does not serve as an important source of either of these elements. Iron is typically obtained from oxide ores such as hematite and magnetite.

We are given that the iron ore contains 92.0% pyrite, and pyrite, also known as fool's gold, has a formula of FeS2 and is 46.5% iron. So, to find the mass of iron in the ore, we first calculate the mass of pyrite in the ore: Mass of pyrite = 92.0% * 50.8g = 46.736g. Next, we calculate the mass of iron in the pyrite: Mass of iron = 46.5% * 46 ...
