The first pilot processing was carried out in spring of 2017.
In a year the specialists of the Ridder Mining and Processing Works have mastered the technique to obtain concentrate from the Dolinnoye deposits ore.
Since then the factory has assembled a Knelson centrifugal concentrator.
The volumes of ore processing are expected to increase each year – from 500 thousand tons in 2019 to some 1 million tons in 2020. (Ukrainian metal)
