May 02, 2021 02 Hematite iron extraction process. As a weakly magnetic iron ore, the hematite contains a small amount of magnetite, uneven dissemination size of impurity, and more fine particles. Due to its complex ore properties, gravity separation, flotation, magnetic separation, and the combined process are often used for separation.
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50 needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
The DNi Process TM is a greener metal extraction technology. In fact it does not produce wet tailings which require containment dams or dumping at sea. Our unique patented process consumes very little acid, typically 30-80kg of acid per tonne of ore processed. Whats more, over 98 of the nitric acid used is recovered and recycled.
