Avaliação Da Granulometria De Alimentação E Dos Produtos Da Etapa Rougher De Flotação Da Usina Do Sossego

Abstract: A usina do Sossego processa um minério sulfetado de cobre e ouro. A etapa de flotação compreende estágios rougher, cleaner e scavenger do cleaner, sendo que os concentrados das etapas rougher e scavenger do cleaner passam por um estágio de remoagem antes de seguir para a etapa cleaner. Ao longo dos primeiros anos de operação da usina, observou-se que a granulometria de alimentação da remoagem estava consistentemente mais fina que o esperado, mesmo considerando-se que a granulometria de alimentação da flotação … Show more

“…Figures 1 to 4 illustrate the two reagent dosing systems at Sossego mill. This mill's flotation circuit is described in detail by Bergerman (2009), Miranda et al (2015 and Rosa et al (2007). The diaphragm pump system has shown a poor operating performance at Sossego mill due to several clogging events, as well as frequent need for maintenance.…”
