Abstract: Sand iron ore has not been fully used because of its low grade and little value in mining. Now it is possible to develope sand iron ore as the need of iron increases greatly and the iron price goes up rapidly. The sand in river contains some megnetic iron predominant sand iron ore which is easy to process and to mine and is not contaminative to the enviroment. Consequently, sand iron ore shows great potential as the supplyment of iron ore; In addition, Hennan is rich in sand iron ore as well as iron ore and water resource; But it is very likely to destroy the enviroment if it is processed improperly in the mining of sand iron ore; Therefore, it is significant to study the potential resource and reasonable mining method of sand iron ore.
