After settling and self-weight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about 1.8 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s. Figures 2.4(a) and (b) show typical wet and dry density and w profiles with depth for ...

the tailings. Unfortunately, such separations are never perfect, and in practice some waste material is included in the concen-trates and some gold remains in the tailings. Middlings, par-ticles that belong in either the concentrate or the tailings, are also produced, further complicating the situation.

Check out page 12 for a comparison of the method. According to this document sluices and jigs are equall in their fine gold recovery. However, the Kelsey jig, Mosley and centrifuges seem to have the ability to collect smaller pieces. I am curious to hear from someone that has piratical experience on both the jig and centrifuge.
Technology Development leader Jim Lorentz discusses how centrifuge technology is helping Syncrude to manage tailings volumes and reclaim the land.
Keywords: tailings dams, waste dumps, centrifuge modelling, stability design. 1 Introduction Tailings dam failures generally result in catastrophic ecological disasters. Failure of an embankment generally results in liquefaction of the unconsolidated tailings mass, which can flow many miles in the surroundings. Because of the potential

If the tailings are recovred by a TPB800 vertical centrifugal centrifuge concentrator,the medium-fine grain gold can be completely recovered. Such sucessfull cases China likes Hunchun Zijin Gold Mine, Shaanxi Shenba Gold Mine and Huanglong Gold Mine are …
Tailings Recycle Wolframite Optimization Design. The wolframite is brittle and easy to smash and produce fine slime, and most of them have fine embedded granularity and more useful metal minerals. The gangue minerals are closely related to tungsten minerals, and the separation is difficult. Many fine grain tungsten can not be recycled.
Knelson gold concentrator design centrifuge for gold concentration . Description of Gold Separator Machine: Centrifuge is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
