  • Mine Tailings Disposal Methods

    16/06/2017· Mining Coal Tailings Disposal As has been pointed out earlier in this section, immense quantities of wastes are produced by coal mining activities Many of the regulations governing these wastes have only recently been enacted, and the Surface Mining Control and Reclamation Act of 1977 (PL 9587) will be a major factor influencing coal mining waste management in the future TheThe global mining industry has been producing a huge amount of waste and so is the Indian coal industry which ranks third in production worldwide Coal Mining and Processing has left a trail of waste dump and tailings in slime ponds This warrants development of processes for recovering value from rejects of yester years In this paper, pros and cons of enrichment of tailings have been dealtCoal tailings reprocessing and fines recovery Mineral
