The General Processing Flow of Ore Beneficiation
With the development of technology, the process of ore beneficiation becomes finer, more effective and automated, but some specific procedures must be concluded in the process of ore beneficiation. Now, letâ€™s talk about the general processing flow of ore beneficiation.
1) Preparations: crushing, screening, grinding, and classifying of ore
We generally choose jaw crushers to break the ore. The broken ore will be transferred to screening equipment, like vibrating screen by transferring machine. Vibrating screen here refers to some large-sized ore-separating vibrating screen, such as ZKS vibrating screen and ZGS heavy ore-separating vibrating screen. Different sizes of ore are separated after the screening process, and then they will be further grinded by grinding equipment to become smaller particles. Generally seen large-sized grinding equipments used by many factories are ball mill, vibrating mill, and so on. Here what should be pointed out is that the granularity of ore grinded by different grinding equipments is different: the particle size grinded by ball mill is a little bit larger, but ore grinded by vibrating mill is much fine and even, but its production capacity is smaller. So, which kind of equipment will be chosen is decided by the requirements and needs of users.
The grinded ore have to be screened again, but this time, we should choose fine separating equipments, such as spiral vibrating screen, ultrasonic vibrating screen, linear vibrating screen, and so on. The production capacity of those separating machines is not large, but they can meet userâ€™s requirements on the granularity of ore.
2) ore separating line: such as heavy separating, flotation separating, electric separating, and so on.
Some separated ore neednâ€™t have fine screening process, those heavy separating, flotation separating, and electric separating will be used only according to the characteristics of materials, because some ore have some specific mineral element, which cannot be separated by general physical separating. The choice of separating machine is depending on the nature of ore, and its elements.
3) dehydration: including concentration, filtering, and drying
Different ore may need different kinds of dehydration, although the general process of dehydration is concentrating, filtering, and drying. This is only the general ore separating line, but with the continuous improvement of equipments, more effective and automated flotation machine with higher performance will be produced, and at that time, the ore beneficiation will be more energy-saving, and effective.
