Thermo Fisher launches next generation in-stream analyser for processing plants – International Mining

Thermo Fisher Scientific has launched its next generation Thermo Scientific™ AnStat-430 Online Sampling and Elemental Analysis Station and the MSA-430 Multi-Stream Analyser, online systems designed for, it says, accurate, real-time elemental analysis of mineral slurry streams in processing plants.

While both systems take a representative sample from the slurry stream for the MEP-400 analysis, the AnStat (pictured above) is best used in single stream operations, while the MSA powers the analysis of multiple streams, the company explains. Both analysers now feature the Thermo Scientific MEP-400 Multi-Element Probe, which, it says, significantly improves analytical performance and lowers detection limits to help customers recover more valuable material even in low grade tailings.

With the latest X-ray tube technology, the MEP-400 probe offers a 10-fold improvement in copper lower limit of detection compared with previous versions. By using an air-cooled low-power X-ray tube in place of traditional radioisotope sources, the probe improves safety, simplifies compliance and reduces operating costs, according to Thermo Fisher Scientific. Use of a modern Silicon Drift Detector and Digital Signal Processor increases the probe’s performance and count-rate throughput, improving accuracy across a wide range of elements without the need for cryogenic cooling.

Used with the AnStat and MSA, the MEP-400 enables customers to gain a more accurate understanding of their process in real time, the company claims. This allows them to streamline operations, improve metal recovery, reduce material losses and quickly respond to process changes. The probe is also available as an upgrade for existing AnStat and MSA analyser users extending equipment life, improving performance and providing improved process insights to enable ultimate control

Example applications include base and precious metal flotation circuits; rougher, cleaner and tailings stream analysis; new or expansion projects using online XRF slurry analysers; and upgrading existing AnStat and MSA analyser installations.
