Low impurity content
Lower mercury, arsenic and other metal content impeding subsequent processing of concentrates.
Ultrafine grinding
Conventional polymetallic ore beneficiation technologies provide for grinding size of up to 45 microns. At Ozernaya MPP, rough concentrates are ground to 10-13 microns allowing to produce concentrates with high Zn and Pb content.
Eco-friendly technologies
Ores from Ozernaya deposit are processed using custom technology allowing to utilize the safest chemicals instead of cyanides.
Environmentally-friendly process was also approved by the local community, as the project is implemented using improved technology; it was supported by the residents of nearby villages at community consultations.
