what is the use of iron ore tailings

Ironing out the problems with iron ore tailings with Steqtech

The iron we use today comes from oceans that existed nearly two billion years ago that were teaming with dissolved iron. When the first organisms capable of photosynthesis began releasing oxygen into these iron-rich bodies of water, iron started forming as deposits on the Earth''s crust, which means it is primarily found in sedimentary rocks.
