pH Sensor for Zinc

TT-Zn-pH Zinc pH Sensor

The TT-Zn-pH Zinc pH Sensor has more than 10 years history of providing unparalleled performance in Zinc leaching processes.

Zinc is leached using sulphuric acid, which dissolves the zinc content and leaves the iron and lead precipitates undissolved. However, the process can be inefficient if there aren’t adequate process controls in place, and can lead to lower grade products. Sensors will often drift significantly, and there is constant attack on the pH glass elements from the dissolved zinc complexes. In conjunction with one of our major clients, we developed a pH glass element that resists attack from these zinc complexes, which both improves sensor lifetime and greatly reduced sensor drift.

Additional sulphide resistance has been added to all components and by increasing the physical strength of the body this sensor can also be used in in high velocity, high solid content slurries where other sensors will easily break. The improved accuracy and stability of this sensor has proved itself in improving zinc yields, while the increased sensor lifetime will reduce labour costs and total cost of ownership.

Due to the high resistance qualities of this sensor it is only available in our digital smart sensor technology.
