Why is magnetite mining very dangerous to do? | Yahoo Answers

Jun 05, 2010 · Magnetite is a nontoxic mineral that is a common ore of iron. Some marine molluscs like chitons even use magnetite for teeth (humans use apatite, a calcium phosphate mineral). Magnetite is usually mined from large deposits in open pit mines. Banded iron formations and some metamorphic formations contain significant quantities of magnetite.
