Resumo
Neste trabalho, estudamos o processo de flotação em calcopirita, com ênfase na influência da presença de lodos e argilas na polpa durante a flotação. Para este propósito, a calcopirita foi preparada mecanicamente (trituração e moagem), o material foi classificado (entre a malha 100 e 120 e os tamanhos das partículas foram medidos). No processo, um dispositivo tipo Jig para remoção de lodo e células de flotação Denver para o mesmo propósito foram aplicados. Durante o processo, foi considerada uma redução no consumo de reagente ao manusear a etapa de concentração. Foi observada uma otimização significativa na concentração pela flotação da calcopirita por meio da tela de Jig e os peptizados foram removidos durante a etapa de flotação. O manuseio hidráulico da tela melhora significativamente a remoção de lodo, sendo mais eficiente que o uso do Denver Cell.
