Electrostatic Beneficiation Plant
High-Efficiency and Environmentally Friendly Mineral Separation Technology
Electrostatic beneficiation plants are advanced technology systems that provide physical separation by utilizing differences in the electrical conductivity and surface charge properties of minerals.
They offer high efficiency, low operating costs, and environmentally friendly process advantages, especially in the separation of conductive and non-conductive minerals.
They can be used as an alternative or complementary solution to flotation and magnetic separation systems.
How Does the Process Work?
1 Ore Preparation
Run-of-mine ore is reduced to the appropriate particle size using primary and secondary crushers. The objective is to ensure mineral liberation.
2 Grinding and Screening
The material is brought to the particle size suitable for electrostatic separation. Maximum performance is achieved with fine and dry materials. Optimal distribution is ensured through precise screening.
3 Drying (Critical Stage)
Electrostatic separation takes place in a dry environment. Since moisture content directly affects separation efficiency, the material is dried to a low moisture level.
4 Electrostatic Separation
This is the heart of the process.
Conductive minerals rapidly lose their charge and follow a different trajectory.
Non-conductive minerals are directed to a separate collection zone under the influence of the electrostatic field.
Thanks to this physical difference, high-purity separation is achieved.
5 Product Management
The separated products:
Concentrate (valuable mineral)
Middling (intermediate product)
Tailings (waste material)
are directed to separate lines. The middling product can be re-fed into the process to increase recovery rates.
