Abstract

deposição de rejeitos. esta invenção refere-se a um método de disposição de resíduos a partir da fragmentação e processamento de minérios. o método inclui as etapas de classificação dos resíduos de processamento em uma fração de areia permeável à água e uma fração de rejeitos e deposição da fração de rejeitos e da fração de areia para formar uma estrutura de múltiplas camadas contida por pelo menos uma parede de contenção (14) com a fração de areia formando canais contínuos (12) através da fração de rejeitos (10) para permitir a água contida nos rejeitos e na areia fluir por gravidade, através dos canais de areia, para pontos de descarga de água (16), e recuperação da água (18) dos pontos de descarga de água.
