tailings dam construction

Tailings dam Unlike water retention dams, a tailings dam is raised in succession throughout the life of the particular mine. Typically, a base or starter dam is constructed, and as it fills with a mixture of tailings and water, it is raised. Material used to raise the dam can include the tailings (depending on their size) along with dirt. Sand Tailings Dams: Design, Construction and Operationconstruction of this dam was to use the coarse fraction of the tailings. With this objective, the tailin
