Where Is Mining Waste Stored: Unearthing Responsible Disposal Methods

“What remains as waste in the aftermath of mining operations is commonly known as ‘tailings.’ These tailings consist of the residual material left behind after valuable minerals have been extracted in a slurry form. It’s important to note that the particle size of these tailings plays a crucial role in their management, helping to differentiate between ‘sand’ and ‘slime’ categories, which in turn informs the disposal process (Eriksson and Adamek, 2000). Understanding the distinctions in particle size is vital for addressing the environmental and safety concerns associated with mining waste. As of July 5, 2023, these considerations continue to be significant in the mining industry.”

Mining operations produce various types of waste at different stages, spanning from initial exploration, involving activities such as drilling, to the eventual closure of the mine. Among the different categories of waste generated during mining processes, three major types stand out due to their significant volume: waste rock, tailings, and mine water. These waste materials pose notable environmental and sustainability challenges within the mining industry. Waste rock primarily consists of non-valuable rock and mineral material that needs to be removed during extraction. Tailings, on the other hand, are fine-grained particles left over from ore processing, and mine water refers to water contaminated with various substances from the mining process, making effective waste management and mitigation strategies crucial for sustainable mining practices.

Tailings refer to the residual mineral waste left behind following the extraction of mineral concentrates during ore processing. These tailings are typically housed within a specially designed containment structure called a tailing storage facility (TSF). This engineered facility serves as a secure repository for the storage and management of tailings, ensuring their containment and minimizing environmental impact. The TSF plays a critical role in safeguarding the surrounding environment from potential hazards associated with the disposal of mineral waste.
