During the leaching process in hydro-metallurgical processes, undesirable species may also go into solution. The leachate then needs purification to eliminate these undesirable contaminants.
Aqueous phase contamination can cause contamination of the final product, thus leading to a lower realisable selling price of the valuable product.

Ideally, the concentrations of these contaminants should be monitored on-line in real time.
By using the Blue Cube technology, reliable ionic species concentration information is made available in real time.

The product's distinctive features are:

• Require a clear solution for measurement
• Particulate matter and suspended solids need to be filtered out prior to entering the MQi unit
• Reduce operating costs by eliminating overdosing during purification

Measures impurities and ionic species in solution:

• Impure solution after leaching
• Purified solution feeding to SX and EW

• 4-20 mA current loop analogue data output signals for easy integration into current supervisory control and data acquisition (SCADA) system
• Automatic process control: Grade Process Variable controlled to Set Point
