  Efficient bioimmobilization of cadmium contamination in …

  2022111 · Open-cast mining is a common method used for mining phosphate. In this process, stripped topsoil and waste rock accumulate with low-grade PR to form a large amount of phosphate mining wastelands, which destroy landscape aesthetics, disrupt the balance of the ecosystem, and negatively affect the surrounding environment [2].
