Iron ore dressing plant
There are magnetic iron ore like magnetite and weak magnetic iron ore like liminite, hematite, specularite, and for these two kinds of different iron ore, different upgrading way will be involved. For manganetic iron ore, magnetic separation is prior to be considered to get the high grade iron concentrate. But if magnetic separation is still used for the weak magnetic iron beneficiation, a large plant investment will be needed because it needs strong intensity magnetic separator to work. However, here gravity separation can also work for the weak magnetic iron ore. So when the gravity separation can be used? Firstly, the inlay size of iron granules shall be coarse with clear bounds with the other gangue, and crushing can dissociate the iron grain from the raw gangue. Second, there shall be density difference between the iron granules and the other inlayed gangue. On both conditions, the iron ore can be upgrading by gravity separation machine. Here the iron jig machine has been introduced as the ideal separation gravity separation for weak magnetic iron ore. Test can be done if samples about *5kg can be available.
The main pre-separation methods for the weak magnetic ore is gravity separation and magnetic separation. For the intensity magnetic separation, the CS magnetic separator is usually used with its feeding size of **4mm. The NdFeB material is used for the magnetic separator to deal with the ***5mm ore size. Gravity separation machines are main vibration chute with its feedign size of **5mm and waste-ore-remiving rate of ****0% and jigger of 2LTC***9/8T with its feeding size of **5mm, **0mm, **0mm and the waste-ore-removing rate of ****0%.
