Outotec to deliver gold pressure leaching technology in Russia

Outotec delivers gold recovery technology for Pokrovskiy hydrometallurgical plant in the Russian Far East in the Amur region. The contract was signed with JSC Pokrovskiy Mine, which is a part of the Russian's third biggest gold producer Petropavlovsk Group. Contracting parties do not disclose the contract value but deliveries with similar delivery scope are typically worth of some tens of millions of Euros.

The delivery is based on the basic engineering carried out by Outotec. Outotec's scope of delivery comprises main equipment for pressure leaching process including four autoclaves of 60 m3 with related equipment and a process control system. The equipment will be delivered over the next 18 months.

The Pokrovskiy facility needs new process technology for processing sulphide gold ore. The ore is delivered from Pioneer and Malomir gold mines in the Amur region. The facility produces annually 144,900 oz of gold. The capacity of the new pressure leaching plant is estimated to be 600,000 tonnes of concentrate a year.

"We are hoping to establish a long-term strategic partnership with Petropavlovsk Group. We are able to offer sustainable technology solutions for efficient recovery of gold and this delivery opens up us new passages for other gold projects in Russia and elsewhere. Moreover, this partnership enables us also new research possibilities and resources in Russia", states Outotec's CEO Pertti Korhonen.
