The SONARtrac sonar flowmeter, an online measurement system for volumetric flow rate and entrained gas content, represents an innovative breakthrough in full-bore, non-invasive flow measurement technology. By installing a set of sensors on existing pipelines and leveraging patented passive sonar processing technology, the system “listens to” and analyzes the acoustic signatures of turbulent fluid flow within the pipeline, thereby enabling precise measurements. This technology was developed specifically for flow measurement under the most demanding operational conditions—such as drilling, oil and gas extraction, as well as in three-phase flows involving solids, liquids, and gases, including ore processing and metal smelting.

Non-nuclear impact density meter
Andymer’s proprietary tapping technology generates, acquires, and analyzes vibrations on pipe walls to determine the density of the slurry inside the pipes. Intelligent software distinguishes between valuable vibration signals and ambient vibrations, thereby capturing the unique signature generated by the slurry. Advanced algorithms enable real-time, high-resolution spectral analysis, ensuring highly sensitive and accurate measurements. Compared to radioactive density or ultrasonic density technologies, this technique offers significant advantages: lower maintenance costs, non-contact operation, compatibility with metal or plastic pipelines of any size, no need for routine maintenance, quick installation within minutes, and no disruption to production.

The emergence of SFA’s near-infrared technology stems from the market’s demand for alternatives to conveyor-belt PGNAA sensors. As the industry’s first provider to apply near-infrared technology to online analysis of both organic and inorganic raw materials, we have been delivering elemental and phase-specific online analysis for over a decade to the metal smelting and ore-processing industries, combining highly sensitive analytical methods with reliable and precise sensors. The rapid advancement of Advanced Process Control (APC) has highlighted the outdated state of quality control in the mineral resources sector, which still largely relies on manual sampling—a practice that is severely lagging behind. Leveraging big data and artificial intelligence technologies, SFA has developed highly sophisticated calibration models for real-time measurement of mineralogical and chemical compositions. This approach is not only accurate and versatile but also free from nuclear safety concerns.

The ore grade analyzer PST is a novel and highly versatile technology that is installed on the overflow slurry pipeline of a single hydrocyclone. It is the only system capable of directly and in real time measuring the particle size of the overflow from an individual hydrocyclone. This online measurement provides a reliable, low-maintenance method for determining particle size distribution, enabling systematic optimization of grinding operations. The value of this technology lies in its ability to track the particle size of the overall hydrocyclone group’s overflow based on the contribution of each individual hydrocyclone. As a result, real-time closed-loop grinding control strategies can enhance mineral recovery and improve grinding efficiency while maintaining or even increasing plant throughput. The probe is inserted directly into the hydrocyclone pipeline; it contains no moving parts, requires no sampling, and eliminates the need for complex online sample-handling systems, thereby significantly reducing maintenance requirements.
