Tailings Retreatment: The Next Revenue Source for the ...

Tailings deposited into dams are in the form of a slurry. In 1998, a tailings dam failed at the Los Frailes zinc mine in Spain, causing more than one billion gallons of acidic, heavy metal-laden sludge to spill into the surrounding area, eventually making its way into the Guadiamar River. The spill decimated the area, resulting in massive ...

David John Williams, in Ground Improvement Case Histories, 2015. 2.4 Beaching behavior of mine tailings. The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF.The tailings may be discharged from a single ...

Tailings Management - Teck

Tailings are a common by-product of the mining process. They are typically created as mined ore is crushed, ground and processed to separate the valuable minerals and create a saleable concentrate product. The waste from this process is called tailings.

Innovative Methodology for Sulfur Release from Copper ...

To effectively prevent the accumulation of copper tailings from producing acid mine drainage (AMD) and maximize the comprehensive utilization of copper tailings, the process of oxidation roasting was adopted to release sulfur in the form of SO 2 to achieve the purpose of sulfur recovery later. Based on the AMD risk assessment, thermogravimetric (TG) analysis, and differential scanning ...
