Abstract

a presente invenção se refere a um elemento de coalescência para agregar gotículas de uma emulsão. o elemento de coalescência inclui um substrato de man-ta de não-tecido. um coalescedor que inclui o elemento de coalescência pode tam-bém incluir uma caixa e uma entrada de fluido e uma saída de fluido, cada uma em comunicação fluida com o elemento de coalescência. o elemento de coalescência e o coalescedor podem ser úteis para as emulsões que se formam no processamen-to de cobre por extração de solvente ou por eletroextração, ou para outas emulsões.
