Petropavlovsk’s pressure oxidation investment starting to bear fruit

Russian gold miner Petropavlovsk’s large investment in its pressure oxidation (POX) process over the past decade is starting to bear fruit, nonexecutive chairperson Roderic Lyne said on Tuesday.

The POX Hub, at the site of its first mine Pokrovskiy, allows Petropavlovsk to process not only its own 9.6-million of its refractory ore resources, but also third-party refractory resources. The POX Hub is able to process up to 500 000 t/y of refractory concentrate and poured its first gold in December 2018.
