Liquid Analysis in Mineral Processing

From Advanced Sensor Technologies, Inc.
 

 
This paper describes the process applications that take place after mining and prior to refining as they relate to pH / ORP, dissolved oxygen and conductivity.The implementation of the proper analytical sensors in the common metal extraction processes used today in the minerals industry go far beyond mere indication of status or process upset, but can give us an extremely accurate and meaningful measurement of the process condition. The new generation of analytical sensors can allow us to monitor and control applications never attempted before such as in-situ measurement of the leaching process or the control of chemical addition. Base and precious metal processing operations frequently involve solids / liquid, liquid / liquid and liquid / gas applications in which there are ongoing chemical reactions and/or mass transfer. The meaningful association of measurements with known standards, custom calibration, measured ionic background and temperature will provide reliable results.
