Column Flotation
The company operates a number of pilot plants in the field, presently beneficiating various minerals. A scientific approach is an invaluable tool providing achievable performance and the gathering of sufficient supporting data in order to ensure process flexibility and efficiency. However, pilot plant tests should still be carried out to confirm the accuracy of the calculated data. Critical design features on Column Flotation includes an internal froth discharge launder system, which prevents dead froth areas and ensures sufficient discharge capacity. Wash water systems are designed for ease of operation and are also height-adjustable, with flushing ports ensuring on-line cleaning when necessary. Depending on the application, interface level control is achieved through a relative conductivity probe or a float and ultrasonic system. Furthermore, the internal feed distribution ensures equal distribution throughout the cross-sectional area of the entire column. Excessive feed fluctuations can be eliminated by implementing a column flotation feed/tail sump arrangement, resulting in excellent metallurgical performance. PrepQuip offers three different types of Sparger systems, namely an Air-only SpringSparge Sparger, a Water and Air Gas-Sparge Sparger, as well as In-line Spargers. The selection of a sparger system depends on the application and is determined by the results of pilot plant test work.
