Abstract
For the first time the authors have shown the possibility to disintegrate phenacite-containing flotation concentrate by 93 % solution of sulphuric acid, which provides transformation of ~92 mass % beryllium from the concentrate to water-soluble sulphate. The further enhancement of the completeness of the concentrate disintegration up to ~98 mass % is ensured by application of mechanoactivating preparation of the concentrate for sulphatization.
