In 2000, the Aural Gold Mine in Baia Mare, Romania, released about 100,000 m 3 of gold mill tailings into the Tiza River, a tributary to the Danube River, resulting in a substantial fish kill, with calls for limitations or even a total ban on the gold industry's use of cyanide ( UNEP/OCHA,

Gold Mining and Submarine Tailings Disposal: Review and Case

Gold Mining and Submarine Tailings Disposal: Review and Case

Environmental impacts associated with submarine tailings disposal (STD) of gold mine wastes vary widely among the relatively few cases studied. The principal contaminants of concern surrounding most gold mines are arsenic, mercury, and cyanide, although antimony, thallium, lead, zinc, and copper may also be important in particular mines.

Treatment of Cyanide Heap Leaches and Tailings. 3 After leaching has been completed, such that no further recovery of gold will occur, the spent ore and remaining cyanide solution become wastes. There are several approaches to the decommissioning of cyanide contaminated ore heaps and neutralizing of cyanide solutions.

Gold Vat Leaching Mineral Processing &Metallurgy

Gold Vat Leaching. The dimensions of vats vary with the work to be done. In calculating the capacity of a leaching vat, the volume of a ton of raw ore may be taken at from 22 to 28 cubic feet when dry, and from 20 to 26 cubic feet when wetted down. Tailings sometimes occupy 30 cubic feet per ton or even more.

Inactive tailings impoundments also are receiving more attention due to the longterm effects of windblown dispersal, ground water contamination, and acid drainage. In many cases, the costs of remediation can be considerable, exceeding the costs of original design and operation of the tailings impoundment.

Deep shaft mining is problematic for a different reason. Rock is mined, crushed, good stuff (minerals that usually compromise <<5% of the rock) removed, and the rest (tailings) discarded. The tailings cannot go back down the mine because it is crushed, has lots of air space, and its volume is significantly multiplied.

mineralogy of gold tailings are quartz (37%), amphibole (30%), illite (26%), chlorite (4%), and pyrrhotite (3%). The particle size distribution of the tailings was determined by a laser diffraction analyzer that utilizes diffraction patterns of a laser beam passed through minerals ranging from nanometers to millimeters in size.

In conventional tailings deposition the beach slope is very low, often around 1% (less than 1 degree) and facility design can be flexible if there is a slight variation in this parameter. However, for thickened tailings where the variation is often greater with increased beach slopes, this can have a big impact on embankment design heights.

Gold Mill Tailings Tailings are, by definition, fineparticle residues of milling operations that are devoid of metal values. Particlesize distribution is one of the most important ways of characterizing tailings. The mining industry distin­ guishes "sands"and "slimes"as components of tailings (usually + 200 mesh, 74 IL, for sands).

Environmental impact of mining

The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes. Besides creating environmental damage, the contamination resulting from leakage of chemicals also affects the health of the local population.
