Separation process of iron ore,iron ore magnetic

2020-9-8  The flotation process is mainly used for the separation of fine-grained and particulate weakly magnetic iron ore, including two process flows of positive flotation and reverse flotation. Among them, the positive flotation process is suitable for quartz hematite ore without easy pumice gangue, and the reverse flotation process is suitable for ore with easy flotation gangue.

2020-8-31  It is mostly used to process coarse concentrates of gravity separation and magnetic separation to obtain high-grade iron ore. There are two types of reverse flotation technology for iron ore, one is anionic collector reverse flotation method, the other is cationic collector reverse flotation method. The specific contents of the two reverse flotation methods are as follows:

1983-4-1  The market requirements for higher-grade concentrates of iron to improve the productivity of the iron and steel industry, has increased the importance of the flotation process with respect to the conventional preconcentration of ore by gravity or magnetic separation. The flotation method most commonly applied is the one that is based on cationic flotation of silica and silicates (reverse flotation),

DRY BENEFICIATION OF LOW-GRADE IRON ORE FINES

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic [1,5]. Wet and dry low-intensity magnetic separation (LIMS) techniques are used to process ores with strong magnetic properties such as magnetite while wet high-intensity magnetic separation is used to separate the Fe-bearing minerals with weak magnetic properties such as hematite from gangue minerals. Iron ores such goethite and limonite are commonly found in tailings and does not separate very well by either technique [1,5]. Magnetic methods present challenges in terms of their low capacities and in terms of the requirement for the iron ore

Developments in the physical separation of iron ore

2015-1-1  In iron ore beneficiation, LIMS are used to treat magnetite ore, while high-intensity and high-gradient magnetic separators are used to treat oxidized iron ores. Because different iron ores possess different magnetic characteristics, it is very important to develop an optimized flow sheet to maximize the Fe grade of the concentrate with high Fe recovery while at the same time minimizing operating costs.

The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others.
