AB  - Microbially induced carbonate precipitation (MICP) could be a potential green 
      solution to resolve the issue of heavy metal releasing from the sulfide tailings. 
      However, detailed mechanism of heavy metal-biomineralization in sulfide tailings 
      and impact of procedure parameters on in-situ applications remain unexplored. We 
      systematically investigated the biomineralization process in the column tests for 
      a better understanding of the mechanism and effects on the inhibition of cadmium 
      (Cd) releasing from sulfide tailings. Results revealed that uniform and efficient 
      mineralization in the tailings column occurred under bacterial concentration of 
      1 x 10(8) cfu mL(-1), bacterial retention time of 3 h, concentration of 
      mineralization solution of 0.25 mol L(-1), and flow rate of 1.5 mL min(-1). The 
      leachable Cd concentration decreased 80.7% after 7 mineralization cycles. From a 
      suit of characterizations, bacteria can adhere on the tailings and acted as the 
      nucleation sites to induce the mineralization of Ca and Cd (to (Ca0.67, 
      Cd0.33)CO(3) and calcite phase); eventually, tailings particles were coated with 
      the growth of mineralized carbonates, resulting in a reduction of exposure for 
      tailings (especially sulfur). And thus, Cd release was inhibited. Results from 
      this study will provide a fundamental basis for future in-situ applications of 
      MICP to mitigate heavy metal pollutions.
