Outotec has successfully completed the acquisition of the majority of the shares in Biomin South Africa Pty Ltd and certain assets from Biomin Technologies SA in Switzerland. Outotec now has the full intellectual property and marketing rights of BIOX® bio-oxidation technology. The transaction was announced on July 31, 2015, but the acquisition price was not disclosed.

Biomin’s BIOX bio-oxidation is a proven method for the pre-treatment of refractory gold ores, and it complements Outotec’s portfolio of gold processing technologies. BIOX’s annual business volume has been some millions of euros, with flagship installations including Runruno in the Philippines and Kokpatas in Uzbekistan.

“Combining the BIOX bio-oxidation expertise with our engineering capabilities and proprietary equipment, such as grinding mills, reactors, cooling towers and thickeners, we can provide gold producers complete sustainable plants with life-cycle services”, said Robin Lindahl, head of Outotec’s Metals, Energy & Water business area.
