Moly Thickening / Dewatering. A high rate thickener thickens the moly concentrate.

Tailings Pond an overview ScienceDirect Topics

The tailings ponds were built without any proper base liner, separation, and refining activities irrespective of the raw material. Mining leads to encroachments on nature and requires energy, fuels, and chemicals, which have to be remediated accordingly. If this

Tailings

Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward finding alternate uses.

Mine tailings are the waste solid residuum after separation of valuable minerals from economically worthless minerals (gangue). After extraction and beneficiation, the residuals from mineral recovery are normally discharged as a hydraulic fill (aka slurry) composed of finely ground gangue (sub-micrometer to sand-sized particles), chemicals, and

Tailings.info What Are Tailings? Their nature and production

The engineering characteristics of tailings are in most instances influenced by the degree of thickening and the method of deposition. It is therefore essential that while investigating the properties of tailings that the physical characteristics and material parameters (e.g. beach slope angles, particle size segregation, water recovery) that can occur as a result of varied deposition

Primary Separation Cells Oil Sands Magazine

Mar 23, 2016 This high density is important for good separation in the vessel and proper tailings deposition, which performs better at higher densities. However, this is typically the limit of the system's pumping capacity. If the density it too high (greater than 1.6 t/m³), the underflow is too dense to be pumped out by the centrifugal pump.

Feb 10, 2018 Tailings’ characteristics markedly depend on mineralogy of the ore deposit and the refining method selected. One feature typical for tailings pond is grain size differentiation. Sand and silt rich layers alternate throughout tailings bed (Parviainen et al., 2012, Heikkinen and Räisänen, 2008).

WO2014066668A1 Method for rare earth and actinide

Methods are described for the recovery and separation of the rare earth elements from ore, tailings, or any other solid source. The methods described utilize mechanochemical methods for creating chemical compounds and complexes which are suitable for separation from the original materials. The rare earth element compounds created from the solids are then able to be extracted from the remainder

Red mud

Red mud, formally termed bauxite residue, is an industrial waste generated during the processing of bauxite into alumina using the Bayer process.It is composed of various oxide compounds, including the iron oxides which give its red colour. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 1.5 tonnes of red mud are

Froth Treatment Explained Oil Sands Magazine

Mar 08, 2016 Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.
