The scalping mixer tanks, used to mix the crushed ore and water to maintain a uniform discharge for further processing for the Henrietta Gold Mine. These tanks must process a water and ore mixture with a Specific Gravity of 1.5 and an Abrasion Index of 20. Mixers are required in the scalping tank to maintain the uniformity of the ore and water mixture, and to keep all the ore particles in suspension. Due to the abrasive nature of the ore, the selection of a mixer was an important consideration. Fluid Systems of Texas USA were referred to DBS Manufacturing for a solution to mixing in the scalping tanks for this project.
CASE STUDY

Mixers for Gold Mine
- Mining
- Hyperbolic Mixer
- Arizona
Solution
This mixture is very abrasive. One way wear can be reduced is by using an efficient low speed mixer. Low mixer surface speed minimises mixer wear. The rotor design chosen for this application is the DBS hyperbolic rotor.
Hyperbolic mixers are efficient low speed mixers which are frequently used to mix large volumes in water treatment plants. These hyperbolic mixers are normally made from fiberglass which would not be suitable in the Scalping tank application.
The DBS hyperbolic rotor is unique in that it can be made from nearly any material that can be laser cut. For this project 304 stainless steel was chosen. To further enhance the durability, the rotors were coated with CeRamKote 54. This coating has high abrasion and corrosion resistance.
Results & Benefits
- Efficient mixing. For optimal further mineral processing
- Maximised service life. Lower cost, greater productivity
- Custom solution. Expert diagnosis resulted in superior product delivered that maximise value for the customer
