Abstract

"PROCESSO PARA REDUçãO DA QUANTIDADE DE áGUA CONTIDA EM POLPAS DE MINéRIO NIQUELìFERO OXIDADO". Neste processo para redução da quantidade de água contida em polpas de minérios niquelíferos oxidados, a polpa é diluída com água, injeta-se uma solução aquosa de um floculante baseado num copolímero de ácido acrílico, deixa-se a mistura decantar, e separa-se então o subfluente e o transbordo.
