Metso Outotec launched the HRCe high-pressure grinding roll (HPGR). The HRCe offers decreased installation CAPEX over predecessor competition. It provides maximum productivity through superior grinding efficiency, the supplier reported.

The original HRC launched in 2014 and featured flanges and a non-skewing design. Customer input drove development of the new model, Metso Outotec reported. Compared to predecessor competition, the HRCe offers an energy efficiency increase of 15%, a 24% lower circuiting load, increased throughput of up to 19%, and reduced edge effect and downtime.

Separately, Metso Outotec released the next-generation Courier 6G SL on-stream analyzer for direct measurement of gold, platinum and other metals from ore feed, concentrate and tailings. It has been adopted by Agnico Eagle’s Kittilä mine, and offers accurate real-time elemental analysis measurement, the supplier reported.

Compared to predecessor competition, the Courier 6G SL has a more powerful X-ray tube and optimized measurement channels. It combines Wavelength Dispersive X-ray Fluorescence and Energy Dispersive X-ray Fluorescence technologies with a high-power X-ray tube for unparalleled measurement performance, Metso Outotec reported. It features an automatic internal reference measurement for guaranteed stability under changing environmental conditions.
The analyzer can measure up to 24 individual process streams. It is described as ideal for applications where gold is recovered with other metals.
