The present study aimed at characterizing the direct role of plant roots in tailing mineral weathering and secondary mineral formation in a compartmented cultivation system. It was found that root activities accelerated the weathering of biotite-like minerals via Fe(II) oxidation coupled with Fe(III) and Si dissolution.
The mean values for the biotite chloritization indicator range from 0.13 to 0.74 (N = 24: S2 and S3 Tables). In the control experiment with samples No. 1 and 7, the biotite chloritization alteration indicator in sample No. 1 had a mean of 0.33 and a standard deviation of 0.12. Sample No. 7 had a mean of 0.22 and a standard deviation of 0.08
