Figure 1: Modified centreline raise of an tailings storage facility (#169; Jon Engels) Introduction. A conventional impoundment is a surface retaining structure designed to store both tailings and mine
As there is seldom enough ground available on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to
While these construction principles can be applied to all types of mill tailings dams, each area, climate, and subsequent use requires some modification in the various design parameters. Due consideration to the various parameters will result in a stable, functional disposal system, constructed and maintained at reasonable cost.

Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids

The purpose of a TSF conceptual design, is generally to provide a cost estimate for comparison or budgeting purposes (Feasibility Studies), and to gain approval from the relevant authorities if a change in tailings disposal methods is required, or if it forms part of a Mining Proposal for a proposed mine site.

Tailings Facilities After uranium is mined and milled, the tailings—the crushed up rock which formerly contained uranium—is typically disposed of at the mining and milling site. In the United States, the Nuclear Regulatory Commission (NRC), the federal agency regulating all aspects of the nuclear fuel cycle except uranium mining, regulates all aspects of tailings management and disposal.
