ANALYSIS compensation, an internal VGA CMOS camera, an interactive touchscreen with point-and-shoot capability, and Wi-Fi & Bluetooth connectivity.
In addition, the TRACER 5i provides added convenience for in-situ use, such as an EasyAccess™ rail mount and the ambidextrous Relaxed Grip Strap™. The TRACER 5i retains the unique ability to use an air, vacuum or helium beam path and interactive control of the measurement excitation conditions for optimised data collection, especially for light elements, such as sodium. The new PC software preserves the TRACER’ s comprehensive ARTAX™ analytical software features for complex materials, but has a more streamlined workflow, and now incorporates EasyCal™ software to provide simple correlation fits for standard materials.
The new TRACER 5i covers a wide range of applications and materials from everyday pointand-shoot testing to the ever-changing complexities of advanced applications and research. In mineral exploration, the TRACER 5i can thoroughly and accurately analyse the elemental composition and identify standard or complex ores and rock types. The TRACER 5i is capable of analysing a vast range of sample types.
Terry Smith, Director of R & D for Bruker’ s Handheld-Mobile-Portable XRF Business, added:“ The original TRACER has been a popular product for many years, providing the trained user with far more capability than traditional point-andshoot handhelds. Our experienced handheld XRF development team is excited to launch the new TRACER 5i which incorporates user experience suggestions from TRACER customers with particularly complex and varied measurement requirements.”
The new TRACER 5i complements Bruker’ s industrially focused line of handheld XRF analysers, the S1 TITAN Series, and is designed for customers who need both point-and-shoot solutions, as well as specialised analysis.
On-line analysis at Meadowbank
At the annual Canadian Mineral Processor( CMP) Conference in Ottawa on January 17, 2017, Tom Strombotne, Product Manager Minerals Beneficiation at Thermo Fisher, presented a paper on how the Meadowbank mine in the Kivalliq region of Nunavut in Canada uses an online particle size analyser to optimise the grind size and improve gold recovery. The mine opened in 2010 and from 2010 to 2014 a total of 1.8 Moz

of gold was produced. The milling rate is 4.2 Mt per year with an average mill throughput of 11,900 t / d or 496 t / h. Gold production in 2015 was
381,804 oz and silver was 221,000 oz, and Meadowbank was Agnico-Eagle’ s largest gold producer in 2015.
Strombotne discussed in detail how the particle size analyser acquires its sample from a static sampler located at the primary cyclone

overflow and provides particle size and percent solids analysis in real time. Continuous control of the final grinding circuit product size is important to minimise gold losses. At Meadowbank Mine, the on-line particle size analyser has been employed successfully to achieve the targeted final grind while coping with frequent ore type changes, leading to a substantial increase in revenue by minimising gold losses and overgrinding.
“ Gold plants have successfully deployed online analysers to gain continuous, real-time accurate and reliable analysis of grind size – and have been able to achieve the targeted final grind – for many years. The live monitoring of the final product particle size leads to a maximum
