The samples from mine tailing effluents sampled at sites 2, 3 and 4 are drained to the salt collector; however, at the time of sampling site 2, the effluent flowed into the Cardener River. The rest of the samples from mining effluents (site 1), natural origin (sites 5 and 6) and uncertain origin (sites 7, 8, 9 and 10) are not drained to the ...

This sample configuration was selected to assess the horizontal variability at various scales, and to improve the estimation of the variograms by providing pairs of points at different distances and orientations. Sampling was limited to the northern section of the tailings due to the rubble and soils later deposited on the southern section.

The δ 26 Mg values of a halite sample from the Middle Devonian Prairie Formation are −0.63 to −0.55‰ (AW86-46) and δ 26 Mg values of −0.82‰ to −0.96‰ (CAR12–2 & 12–3) are measured for halite samples from the Lower Silurian Carribuddy Group. The halite sample from the Lower Cambrian has δ 26 Mg of −0.91‰ (Siberia-2).

Sampling strategies for tailing facilities are in many ways different from sampling ore bodies. For instance, the cost of systematic sampling is much lower due to the comparatively easier material access and removal (Kossoff et al., 2014). In addition, tailing bodies such as those that resulted from metallurgical processes in the Witwatersrand ...

Raw Halite Specimen Single Sample, 3" Halite is commonly known as table salt. This soft, white to transparent mineral grows into cleavable cubes. Useful for lessons in cleavage planes and how evaporite deposits form in nature. This mineral is an excellent example of cubic cleavage - when broken Halite will continually break into smaller cubes. ...

The probabilistic sampling processor and the probabilistic tail sampling processor policy work very similar: based upon a configurable sampling percentage they will sample a fixed ratio of received traces. But depending on the overall processing pipeline you should prefer using one over the other. As a rule of thumb, if you want to add probabilistic sampling and...

The impact of salt from the potash tailing piles is reflected in the surrounding ecosystems, which leads to anthropogenic salinization of ground water, freshwater systems and soil . Due to the limited higher plant vegetation in the surroundings of the potash tailing piles, biocrusts appear to play an important role.
