Aktogay bio-leaching project reaches design capacity
The Aktogay bio-leaching complex, which the holding helped build since 2021, has reached its design capacity of 50 million tons of sulfide ore per year — double the previous 25 million.
The complex includes a 3,000 m³ inoculation pond, TK-100/200/300 process tanks and bio-oxidation lines. It is the first project of this scale in Kazakhstan.
