Design and Construction of a Tailings Dam over an Ancient Tailings Facility at La Parrilla Mine

Floods from tailings dam failures.

This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...

Preventing acid mine drainage from mine tailings

Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...

Diversion of Water from a Tailings Dam

Superiority of Filtered Tailings Storage Facility to Conventional Tailings Impoundment in Southern Rainy Regions of China

In order to evaluate the superiority of a filtered tailings storage facility (FTSF) to conventional tailings impoundment in the southern rainy regions of China (SRRC), the tailings slurry leakage and pollution accident occurring at the wet tailings dam (WTD) of Yinshan were analyzed, the properties of the tailings were tested in a laboratory, and the possibility of tailings liquefaction was eva...

The mineralogy of arsenic in uranium mine tailings at the Rabbit Lake In-pit Facility, northern Saskatchewan, Canada

A detailed investigation of the mineralogy of As in the tailings of the Rabbit Lake uranium ore processing facility was conducted. The milling/ ore extraction process was sampled at three different locations to obtain information about when, where and under what condition secondary As phases form. These samples were compared with four samples of varying As content from the Rabbit Lake in-pit ta...
