Deposites of high grade magnetites occur in a number of places, the best known. being in Sweden. When pure, magnetite contains 72.4 % iron, the high grade ore. contains more than 60 % iron with phosphorus-containing minerals, e.g., apatite, as a common impurity. Low grade magnetite deposits are also worked in many.
