Hydrocyclones for Slag Flotation Plant

Air is injected into the flotation cells, and foaming agents are added, creating a froth. slag ore particles, due to their relatively light weight, become a part of this froth, while heavier particles, such as iron ore, do not. The slag-rich concentrate, containing 20 to 40% slag, is then separated from the solution for further processing.

Slag Flotation Plant

Crushed ore (containing 1 to 2% slag), along with water and a lime slurry, is fed into a ball mill. This rotating drum contains steel balls that further crush the ore to a fine powder. When the ore slurry emerges from the mill, it is fed to a rake classifier. Particles that are too large to pass from the classifier are returned to the mill, while the overflow is discharged to flotation cells.

Hydrocyclones for slag Flotation Plant

The hydrocyclone for slag flotation plant is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. It is often used to separate “heavies” from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid.

For grinding circuit applications, the hydrocyclones increase circuit capacity by minimizing the quantity of fines bypassing to the underflow stream. The hydrocyclones achieve these results by maximizing the air core diameter created within the rotating mass of fluid in the cyclone. These effects are proven in both laboratory testing and full scale plant operation.

Slag Separation Hydrocyclone Benefits

  • 1. Finer, sharper particle separations at high capacities
  • 2. Fewer cyclones needed for optimal performance
