bba Tailings disposal: choosing the right technology

2019-12-18  Tailings disposal: choosing the right technology. Mining operations generate much larger tailings volumes than mined volumes, and it is imperative that mine operators dispose of these tailings. This can be a complex process, especially given the hauling distance to reach the disposal sites in
