The Boac River Tailings Spill Disaster of 1996. On March 24, 1996, another massive tailings spill at the Marcopper Mine filled the 26-kilometer-long Boac River on the island of Marinduque with 3-4 million tons of metal enriched and acid generating tailings. The spill happened when a badly sealed drainage tunnel at the base of the Tapian Pit burst.
March 24, 1996 is the date often remembered when one of the worst mining disasters in Philippine history occurred on the small island province of Marinduque.. The tragedy struck the island when one of the Marcopper dams, the Mt Tapian pit that contained toxic mine tailings from San Antonio, collapsed and flooded the Makulapnit waterways all through the Boac river
Dec 02, 2019 With increasing metal prices and declining ore grades, new mines are getting larger and mine waste disposal and management have become more difficult, particularly from an environmental perspective. While technologies keep on improving, the available space for terrestrial mine waste disposal is limited. Thus, several coastal countries still consider deep-sea tailings

Tailings are discarded back to the water, and the product is loaded onto barges and hauled away. Two principal types of bucket dredges are used. One has an inclined belt-conveyor stacker to discharge the coarse fraction of washed tailings well astern of the haul, and sluices to dis- charge the sand fraction a short distance astern.
Dec 10, 2020 For every barrel of bitumen extracted in Alberta, about 1.5 barrels of non-recyclable tailings volume are produced. In 2019 alone, an estimated 1.5 million barrels of tailings were produced, which ...
Uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. These tailings pose serious environmental and health risks in the form of Randon emission, windblown dust dispersal and leaching of contaminants including heavy metals and arsenic into the water. 5
Within a year waste was flowing through the overflow. The dam continued to leak acidic and metal enriched waste since 1994 and was in danger of collapse. Boac River No risk assessments or Environmental Impact Assessment were conducted on the Tapian Pit before using it as an impoundment for tailings in 1992.
tailings flats into the ocean may have substantial adverse environmental impacts. Due to the sub-stantial amounts of soluble salts in the tailings and the strong ability of chloride in sea water to complex metals from the tailings, there is consid-erable potential that a highly acidic, metal-enriched, and environmentally detrimental plume
Dec 22, 2020 The amount of total rare earth elements varies from deposit to deposit, but each deposit is enriched in the heavy rare earth elements, which are far less common than the light rare earth elements. Total rare earth elements range from zero to nearly 2.2 for the waste and tailings piles and zero to nearly 4.8 for ore.
