The Rhosonics SDM (Slurry Density Meter) has taken up the task of improving the operational efficiency of Minera Mexicana ‘La Ciénega’, a Fresnillo PLC mine located in Durango, Mexico. The mine, which has been operating since 1992, engages in exploration, mining, and processing of gold, silver, and other minerals.
The purpose of testing the Slurry Density Meter was to evaluate an alternative to the existing nuclear density meter for monitoring density in the tailings thickener underflow. This measuring point is crucial since they need to track how much slurry is being transferred to tailings at all times. Additionally, the company aimed to optimize the thickener underflow to improve operational efficiency.
The Rhosonics’ SDM Slurry Density Meter was an ideal choice due to its reliable and real-time measurement results. A 30-day trial was conducted to evaluate the use of a nuclear density gauge and the Rhosonics density meter. The SDM proved to be a better option than the existing radiation-based technology as it coped well with the measuring task and process challenges. The SDM uses ultrasonic technology, which eliminates the need for government licenses and the cost of employing and training specialist employees for maintenance and calibration tasks.
According to the client, the SDM was able to successfully measure density, reliably and accurately, which enabled them to efficiently monitor and control the slurry transfer process from the thickener underflow.
Minera Mexicana ‘La Ciénega’ has a production capacity of 4,000 tons per day, making it essential to have reliable and efficient processes in place. With the Rhosonics SDM, the mine now operates with increased efficiency and productivity. The successful implementation of the Rhosonics SDM at Minera Mexicana ‘La Ciénega’ sets a precedent for other mining companies to follow, improving operational efficiency using an eco-friendly technology and driving the mining industry forward.
