Metso is extending its hydrometallurgy offering with the launch of OKTOP BIOX Reactor, ideal for the pre-treatment of refractory gold concentrate and base metal leaching.
The new addition is part of the company’s Metso Plus offering and enables enhancing oxygen mass transfer to improve energy efficiency and process performance during the leaching process.
“The OKTOP BIOX Reactor provides increased operational efficiency with the most energy-efficient agitator design available for the BIOX process,” said Waldemar Olivier, senior process engineer, Gold.
“The reactor features a dual-pumping agitator that maximizes surface aeration, increasing oxygen mass transfer and enhances foam entrainment back into the slurry using a novel surface aeration ring. Thanks to its innovative design, it delivers more than 20% energy savings on agitation power, lowering operational costs.”
The company will be offering comprehensive support for the reactor, from design to service. This includes full process design, mechanical guarantees, and test work capabilities. To support steady operational efficiency, Metso’s in-house engineering team will offer monitoring and optimization services.
The modular OKTOP Reactor has over 1,200 installations globally. Metso BIOX technology boasts 14 installations that have resulted in combined gold production of more than 36 million ounces to date. The OKTOP BIOX Reactor features a novel agitator specifically designed for this application.
