Sentence examples for process tailings from inspiring English sources

In this study, optical microscopy, scanning electron microscopy, electron microprobe, X-ray diffraction and X-ray absorption fine structure (XAFS) spectroscopy (including both XANES and EXAFS regimes) were employed to determine the mineralogical composition and local coordination environment of As in gold ores and process tailings from bench-scale tests designed to mimic a common plant practice.

After this process, tailings are either discharged into holding ponds resembling artificial albeit toxic lakes or discarded into the environment.
