Radiometric Separation in Grinding Circuit of Copper ...

2020-4-21  Lumpy ore after semi-autogenous milling in Copper–Nickel ore processing at the Talnakh factory is studied. The lumpy ore is mainly presented by sizes −80+40 and −40+20 mm. The X-ray radiometric separation tests of the lumpy ore prove their efficiency in production of concentrate and tailings. The strength characteristics and the Bond work index of the concentrate are determined. The ...
