:: Outotec to Deliver Technologies for Zinc Plant for Met-Mex Peņoles in Mexico


Outotec has agreed with Peņoles Group to provide zinc production related technologies to the Met-Mex Peņoles' zinc production facility in Torreon, Mexico. The contract, valued at approximately EUR 24 million, has been booked in Outotec's first quarter order intake.

Outotec's scope of delivery includes proprietary Pure Jarosite process, feed pre-treatment system for the roasting process, mercury removal process and OTOVENT quench scrubber for off-gas treatment. Outotec will also deliver installation, commissioning and start-up supervision services for the new processes. The equipment will be delivered and taken into operation in 2018.

With Outotec's solution Met Mex Peņoles will be able to treat finer zinc concentrates, improve the efficiency and capacity of its roasting process and reduce the gaseous emissions of the operations. The silver, zinc and lead recovery at the calcine leaching plant will be improved significantly by the newly commercialized Outotec's Pure Jarosite process.

In 2015, Outotec delivered atmospheric direct leaching process and the OKTOPŪ reactor plant for the same project and this order complements the previous one.

"We have partnered with the Peņoles Group for decades and are again proudly supporting their efforts to improve resource efficiency with our technologies. This addition to their zinc process will maximize valuable metals recovery while reducing environmental impact of the operations", says Kalle Härkki, head of Outotec Metals, Energy & Water business unit.
