ABSTRACT
We analysis the table 4, the test results show that: with strong magnetic strength increases, reduced iron concentrate grade, recovery rate, when the magnetic field strength is 0.97 T, the iron ore grade of greater than 60%, greater than 60% recovery
1 INTRODUCTION
Iron ore is the main raw material for the steel industry, China is the world’s largest iron ore producer, accounting for about 20% of the world iron ore production. China’s iron ore reserves are large but not rich and the average iron content of only 33%. Most are small deposits, metallogenic factors, so the type of ore complex, multi-component large proportion of associated minerals.
