O processo de eletrocoagulação foi investigado na recuperação de prata e ouro. O efeito da alteração do pH e da polaridade foi estudado numa célula de eletrocoagulação descontínua utilizando eléctrodos de alumínio-ferro. Ao trabalhar com os eléctrodos de alumínio como ânodo, sem alterar a polaridade dos eléctrodos a pH>11, as percentagens de recuperação de ouro e prata aumentaram. Nos ensaios com mudança de polaridade, as percentagens de recuperação aumentaram com a diminuição do pH, com a percentagem de recuperação mais elevada a pH=9,4, o que se deve ao facto de os eléctrodos de ferro estarem menos passivados nesta gama de pH.
