The spent ore are mainly composed of quartz with lesser amounts of calcite, feldspar, chlorite, mica, amphiboles and pyrite as illustrated in the X-ray diffraction pattern of the tailing sample ...

Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, a …

A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments. Mineralogical and microscopic investigations indicated that the dominant mica mineral was phlogopite which was accompanied by plagioclase feldspars. Before beneficiation studies, the particle size …

In addition to traditional geotechnical samplers, ConeTec has designed several specialty sampling systems specific to mine tailings applications. These samplers are designed to collect representative samples in tailings materials ranging from process water, to fluid slimes, to liquefiable sandy silt, to dense beach and dyke deposits.

Zlatna, Romania, Valea Mica tailing dam, 46°09′32″N 23°13′16″E: Data accessibility: ... Data can support the improvement of experimental design in order to obtain enough sample biomass at pot scale when the concentration of toxic elements in the tailing material are large, or to devise a better design of coupled multiple scales ...

This sampling was performed to achieve an adequate evaluation of the tailings, considering sampling points from north to south and from east to west over the deposit area. To the sampling, 1 kg of tailing samples was collected from the surface of the paste-tailing deposit. Sampling considers paste samples from the first 15 cm of the tailings ...
