SDM at Minera Mexicana

Measuring Task

Measuring slurry density in the thickener underflow.

  • Pipe diameters: 125 mm (6 inch)
  • Pipe material: HDPE
  • Solids: 10-65 wt%
  • Density: 1500-1650g/l

Challenge

  • To control density which is very crucial since they need to track how much slurry they are transferring to tailings at all times
  • To improve and optimize the thickener underflow

Instrument used

Solution

The Rhosonics SDM Slurry Density Meter is an excellent choice for this measuring task, because of its reliable, stable, and real-time density measurement results. After a 30 days trial in October 2018, the customer did an evaluation of the use of the nuclear and Rhosonics analyzers. Unlike the nuclear one, the SDM coped easily with all the tasks and challenges.

Furthermore, by using ultrasonic technology instead of nuclear, the customer will save time and money on obtaining government licenses as well as paying specialist employees (RSO) for maintenance and calibration.

Results

Fresnillo is currently using the Rhosonics density meter for three years and the client acknowledged many advantages of using it:

  • No special licenses
  • No radiation
  • High accuracy
  • Real-time and reliable measurements
  • Better control of the process
  • No shielding
  • No restricted area
  • No hazardous material
  • Results
