Chapter 11
Chapter 11 Disposal of Residues McPhail Wagner Aim and Scope No metallurgical textbook would be complete without a Chapter dealing with residue disposal. In this Chapter an overview is given of the aspects which require consideration when planning, operating or closing a tailings dam; it should therefore provide background knowledge for the effective manage-ment of tailings dams. Emphasis has been placed on those aspects which re-quire investigation by specially qualified personnel. In this regard the extent and nature of the requisite investigations have been discussed and the minimum qualifications of those undertaking the work have been given. The bulk of this Chapter concentrates on surface disposal, since at the time of writing underground stope back filling had only been carried out on a pilot scale on South African gold mines. It is however recognised that the volume of tailings sent underground will probably increase and that the remaining fraction will become finer and more difficult to manage.
