The awareness of tailings dam safety monitoring has widened due to the recent disasters caused by failures of such structures. The failure rate of tailings dams worldwide (i.e., the percentage of failed dams out of total) is estimated at 1.2%, compared to the 0.01% rate for traditional water dams. Most of the tailings dam monitoring …

Tailings Recycling. Tailings recycling refers to recovering valuable materials from mine tailings, which are the by-products generated during the extraction of minerals from ore. Instead of allowing these tailings to be disposed of as waste, recycling involves reprocessing them to extract any remaining valuable minerals.
