This suggests that sulfide minerals like pyrite are dissolved at the starting of column experiments. By PF-05105679 Purity & Documentation comparing laboratory and in situ circumstances for columns consisting of only rock layer, SO4 2- leaching concentrations inside the in situ condition were reasonably larger than those on the laboratory situation. These results indicate that in situ columns are exposed to extra oxic circumstances in comparison to the laboratory columns, which would induce oxidation and dissolution of sulfide minerals contained in rock samples, resulting in slight decreases of pH and increases of Eh within the leachate. [63,64]. 3.3.4. Recovery RatioTo evaluate the effects of evaporation and residual pore water, the recovery ratio of collected leachate volume to sprinkled distilled water volume for the laboratory columns and that to rainfall observed in the nearest meteorological station for the in situ columns had been calculated. Figure eight shows the ratios for laboratory and in situ column experiments. For the laboratory columns, the initial recovery ratios of L-T1, L-T2, L-T1-AL and L-T2-Im were 0.63, 0.61, 0.05, and 0.90, respectively, because of packing the rock dried in space temperature within the column. Right after the second collection, the ratios of all four circumstances approached roughly 0.90. This suggests that about 10 of sprinkled distilled water was evaporated throughout the experiment. Below in situ circumstances, the initial recovery ratios of I-T1, I-T2, I-T1-AL and I-T2-Im were 0.20, 0.21, 0.19, and 0.21, respectively. Even so, immediately after the rock sample within the column became wet, the ratios of four cases fluctuated between 0.50 and 1.25. This can be as a consequence of the frequency and intensity of rain, changes in temperature, 13 of 1 Minerals 2021, 11, x FOR PEER Overview humidity, and solar radiation. These factors may possibly affect unstable recovery in the leachate, i.e., unsteady-state infiltration for in situ column experiments.Figure eight.
