  6. 5. Investigation of the zinc re-grinding circuit at Boliden Garpenberg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nils Merum; [2021]
    Keywords : Flotation; re-grinding; Garpenberg; Boliden;

    Abstract : Boliden’s mineral processing plant in Garpenberg wanted to investigate their zinc-regrinding circuit. The re-grinding circuit had performed subpar when running as the total recovery of zinc was lowered and problem with the dewatering of the final concentrates was also noted. Therefore, the zinc re-grinding circuit is currently not being used. READ MORE
