APPLICATIONS FOR MINING INDUSTRY
ONLINE AND INLINE ANALYZERS AND SENSORS FOR PROCESS AUTOMATION
In mining applications SensoTech systems are the perfect solution for diverse measuring tasks. First of all, from copper mining to potassium chloride flotation LiquiSonic® monitors saturations. Also, concentrations and suspension densities. Hence, Numerous customer requests always lead to more and more new measuring tasks and applications.
Sonic velocity measurement in KCl-suspension
Typical separation processes for NaCl and KCl are:
Flotation
Electrostatic separation
Hot dissolution process
LiquiSonic® systems can easily be adapted to accommodate various modified process conditions. In addition, the Controller software manages up to 256 various product characteristics.
Depending on the user access rights, these characteristics may be activated after the sensor replacement or when process conditions change. As a result, this concept ensures the return on investment. And, decrease the response time on changing boundary conditions. For new applications, a complete new calculation model can be created by using process reference values.
More over, The LiquiSonic® analyzer provides a precise inline concentration measurement with real-time monitoring. An automatic concentration-regulated process control prevents the plant from being „blocked“ (process control is too slow) and increases the process yield and productivity. The robust sensor construction and the optional special materials, like titanium, promote long process life.
Additional advantages are:
· Optimum line control and reliable process data
· Increasing the efficiency of clarifier and thickener
· Drift free measurements over years
· Early recognition of malfunctions in a matter of seconds
· Reduced material and energy consumption and costs
Copper-Mining
The LiquiSonic® analyzer provides a precise online and inline H2SO4 and Oleum concentration measurement with real-time monitoring. Additionally, systems monitor and and control the blending to the desired target concentration.
Typical measuring range:
Concentration range H2SO4: 80 to 100 wt%
Temperature range: 20 to 90 °C
Concentration range OLEUM: 0 to 10 wt%
Temperature range: 10 to 60 °C
KCl Hot Dissolution
By using the LiquiSonic® controller 30, up to four sensors can be connected. Thus, allowing the whole process to be monitored at different measuring points including crude salt dissolution, clarification, crystallization unit and KCl thickening.
Installation details:
· crystallizer: sensor length 300 – 500 mm
· pipeline (typically DN 300 – DN 800): sensor length 250 mm
· installation from below by partially filled pipes
Typical measuring range:
Concentration range: 1100 to 1600 g/l
Temperature range: 70 to 110 °C
