Seligdar has made a decision to construct a gold-extracting factory at the Khvoynoye deposit in the Republic of Sakha (Yakutia).
The factory using the technique of direct cyanidation will increase gold extraction by 20% compared with heap leaching.
While heap leaching allows extracting 75% of gold, cyanidation will increase this level to 90%.
The technique was developed and tested at the Ryabinovoye deposit.
Design of the new factory will be completed in 2019.
The commission of the first complex with the capacity of 1.5 million tons of ore is scheduled for early 2022. (Ukrainian metal)
