The development stage readiness:
Tested experimental exploitation order
Description of the development: () An industrial cyanide-free technology for dressing has been created.
Copper concentrate with copper content of 20-22% at its extraction and 45% zinc concentrate at 70% zinc extraction. The cost price of dressing stage for one ton polymetallic ore has decreased 1.5 times.
Zinc output in zinc concentrate has increased to 45 thousand ton per year without decreasing in achieved parameters for copper. The toxic reagent is excluded from production.
