The Dust Hazard in Mining Iron Ore. The

After examining 154 old miners employed in iron mines in Lorraine the authors come to the conclusion that the dust of the mines is not particularly harmful, although after 20 to 30 years it sets up mild changes in the lungs, which, however, are quite compatible with good health. The dust contains from 45 to 55 per cent. of oxide of iron with 5 to 6 per cent. of silica.
