 — From reliable performance and regularly updated data sources, remote sensing technologies based on satellite images have become popular methods to observe and manage natural resources over past decades (Song et al. 2008; Wu et al. 2008; Shirazi et al. 2017; Favretto 2018).Numerous remote sensing-based methodologies of surface …

 — Classification-dewatering can realize the size segregation and water removal of tailings and reduce the volume of tailings and transportation pressure [23].The equipment that classifies minerals strictly according to their particle size distribution, the vibrating classifier is more accurate than the hydroclassifying cyclone [24].In addition, vibration …

 — Mining operations lead to the production of large quantities of mineral waste, such as fluid fine tailings whose disposal is rather challenging. In Brazil, tailings disposal is facing a critical situation due to the large accidents that took place in the last couple of years. As a response to these accidents, the Brazilian Mining Agency became stricter on …

Our approach to tailings management is consistent with the International Council on Mining and Metals (ICMM) Tailings Management: Good Practice Guide, which is informed by the requirements of the GISTM and the …

 — The steel industry in Vietnam currently has more than 300 specialized enterprises participating in steel production and trading. Among them are manufacturers that have created a special mark on the international steel market.In the following article, let's explore the top 10 largest steel millsin Vietnam with MRS Steel, from which …

 — One of the most common methods for managing mine tailings is the construction of tailings ponds or tailings storage facilities (TSFs). These large-scale repositories serve as containment areas for the collected material, allowing for the settling of solid particles and the retention of water before eventual disposal or treatment.

tailings facilities and their consequence of failure. While not exhaustive, it illustrates the enormous volume of tailings that need to be safely managed. In 2001 Davies reviewed tailings facility failures up to that time and observed that all were predictable in hindsight and could have been prevented during the design and/or operational phase.

 — The biggest waste streams both in metal value and in volume in mining are tailings, which create long-term environmental liabilities to the companies (Wang et al., 2014) due to the potential for acid rock drainage generation (Simate and Ndlovu, 2014) from sulphidic tailings.Instead of considering the tailings only as an environmental challenge, …

 — 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 Storage Facilities and Water Storage Dams. Water storage dams are assets built to store or convey water for irrigation, power generation, flood con-trol, industrial processes, or recreational uses. TSFs are used for the storage and management of tailings solids and mine waste. The disastrous environmental and health consequences of TSF ...
