Introduction. Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never efficient, nor is it possible to ...

In iron ore processing plants, different tailing streams are usually transferred to the tailings thickener for partial dewatering and finally transferred to the tailings dam as a single stream. Therefore, the mixing of different tailings streams happens. This way can challenge the process of reprocessing the tailings in the tailings …

5.5 Geochemical Characterization of Tailings Ponds. All studied tailings ponds had an average value of pH < 3.5 (ultra-acid) in surface ( Table 5.2 ). In depth, most ponds had ultra-acid pH, except San Cristobal 1a and 1b which were strongly acid (5.1–5.5). The classification of the different tailings ponds in terms of mean values of ...

Ecological engineering of tailings has been advocated to change tailings' mineralogy, improve physicochemical properties, and accelerate soil formation (i.e. pedogenic processes), allowing the re-colonisation of microbial communities and pioneer plant species (Huang et al. 2012 ). These early settlers, in turn, act as powerful biological ...
