1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.

Beneficiation of Iron Ores. These ores ca n be directly used in the production of iron and steel. All other ores need benefaction and certain processing before they are used in t he production of iron and steel. Low grade iron ores cannot be used as such for the production of iron and SST eel and need to be upgraded to reduce its gangue content ...

1 Single Magnetite Ore Beneficiation Process. Single magnetite ore is often selected by weak magnetic separation method. For large and medium-sized magnetic separation plant, when the grinding size is greater than 0.2 mm, a section of the mill magnetic separation is often used; less than 0.2 mm, two sections of the mill magnetic separation.
