Tailings and Mine Waste Conference

Thirty years of tailings history from Tailings & Mine Waste Caldwell, Jack A.; Van Zyl, Dirk

Abstract

By virtue of its long-running success, and the many contributed technical papers, the proceedings of the Tailings & Mine Waste and predecessor conferences present a good opportunity to review and consider the progress that has been made in the design, operation, and closure of tailings facilities world-wide. This paper explores thirty and more years of tailings facility design, operation, and closure by way of a survey of some of the best and some of the seminal technical papers that have been published in the proceedings of the conferences on Uranium Mill Tailings and Tailings & Mine Waste. The story told in this paper is of the movement from simple upstream hydraulic fill, through larger and higher earth and rock embankments, to thickened and polymeramended tailings. The story told is one of advancing from an emphasis on operation to a modern mind-set of design and operate for closure to integrate closed facilities into a final stable landscape.[All papers were considered for technical and language appropriateness by the organizing committee.]
