Abstract:
THIS invention relates to a process for recovering value metals from ore (50) configured such as to substantively reduce or eliminate the need for a tailings storage facility. This object is achieved through an integrated processing system designed to enhance the ratio of sand residue from coarse flotation (62) to the amount of tailings arising from fine flotation (72), and then blending a proportion of coarse and fine flotation gangue materials into a free draining stack (82).
