Abstract
Description
- a) moer a úmido o minério com corpos moedores para formar uma polpa mineral,
- b) condicionar a polpa mineral com um composto coletor para formar uma polpa mineral condicionada, e
- c) flotar por espuma a polpa mineral condicionada para formar uma espuma e uma rejeito de flotação, separar a espuma da rejeito de flotação para recuperar um concentrado de sulfeto de cobre,
A flotação por espuma pode ser realizada utilizando-se equipamentos e procedimentos conhecidos por um técnico no assunto em flotação por espuma de minérios de cobre.
IS = sulfeto de ferro, NSG = ganga não sulfeto.
