Tailings Wikipedia
The greatest danger of tailings ponds is dam failure, with the most publicized failure in the U.S. being the failure of a coal slurry dam in the West Virginia Buffalo Creek Flood of 1972, which killed 125 people; other collapses include the Ok Tedi environmental disaster in New Guinea, which destroyed the fishery of the Ok Tedi River.
How a Thickener Works Mineral Processing & Metallurgy
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were
Thickener Operating pH and Lime for Flocculation
The thickener could be “sliming” and will produce a dirty overflow combined with a low density underflow. If this is a problem, a reagent called a FLOCCULANT is added to the thickener feed. A flocculent causes the slimes -to form into small masses of mineral. This will make the thickener load settle. Flocculants may be purchased under
Thickener Torque -Rakes & Drive
A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener.

fines (fine waste) and tailings (coarse waste). The tailings and slime fractions are composed of calcitic to dolomitic crystalline minerals with minor quartz, gypsum and traces of yellow secondary uranium salts also found. The fines would be thickened in deep cone thickeners and flotation tailings would be thickened in a high rate thickener
Tailing Disposal Methods and Tailings Dam Construction Design
Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
Conventional Thickeners Solid Liquid Separation
Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away. Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters

For a large thickener demo plant, a series of small hydrocyclones could be incorporated to assess the variations in thickener performance for different tailings gradings. The coarse fraction could be used in filtration trials or in a pipe loop (with thickened slimes) to determine the transportability of the two independent waste streams

slime will collect on the stirring rod. Continue adding the borax solu-tion until most of the glue–water mixture has turned into slime. Be careful not to add too much borax solution, or the slime will become too stiff. A good rule of thumb is to quit adding the borax solution when there is still a little glue–water mixture left in the

For low pulp densities the coarse fraction of the tailings generally settle closest to the discharge point with the finer material (slimes) being carried furthest away. The deposition flow rate from the spigot greatly influences this segregation or if flows from adjacent spigots combine as a single stream further down the beach. For subaerial
