The generation of tailings in the world today is immense, since only ounces or pounds of metals are extracted for each ton of ore processed. In 2022, it was estimated that more than 14 billion metric tons of mining tailings were produced per year in the world. Currently, many environmental problems associated with tailings management in …
Driven by mining volumes, globally generated tailings are estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron per annum. Water conservation and the cost of tailings and reclamation are also becoming increasingly significant factors for sustainable and economically viable mining and long-term survival. Challenging the …
Static liquefaction has been associated with numerous recent failures of tailings storage facilities (TSFs) around the world (e.g., the 2019 Brumadinho failure). These failures lead to devastating consequences for the environment and civil infrastructure as well as the loss of human lives. In this study, we present trends for the mechanical …
Tailings Center was created in 2020 to perform research and educate students, individuals in the mining industry, and regulators from the US and foreign countries. The center has provided many short courses to various audiences and will play a key role in supporting students pursuing the Tailings Engineering Graduate Certificate.
