Written in English
A validation of the Reactive Acid Tailings Assessment Program for Base Metal Tailings model was provided. The concepts upon which the model was based were discussed, and comparisons were made between it and other acid mine drainage modelling approaches. The many processes that the model considers, such as oxygen pore-gas diffusivity, temperature variation with depth, and porewater transport of metals, were also presented.

Net acid-generating capacity was estimated using rapid chemical oxidation (NAG) (Miller and Jeffery, ).Finely-ground tailings samples ( g) were reacted with 15% H 2 O 2 solution (50 mL) at ambient temperature overnight, then boiled for 2 h to remove remaining H 2 O amount of acid generated was determined by titration with NaOH, and the result converted to kg H 2 SO 4 t − by: 4.

It is also important to attain homogeneous mixing of acid consuming materials with reactive mine tailings to maximize the efficiency of this approach.
If not, preferential water flow through the reactive mine tailings with limited basic materials may result in the formation of acidified leachates as illustrated in Fig. The efficiency of non-acid generating tailings, desulfurized tailings, and non-reactive waste rocks as cover materials was demonstrated in previous laboratory and field studies.

Smith Permeable reactive barriers designed to enhance bacterial sulfate reduction and metal sulfide precipitation have the potential to prevent acid mine drainage and the associated release of dissolved metals.
Two column experiments were conducted using simulated mine-drainage water to assess the performance of organic carbon-based reactive mixtures under controlled groundwater flow conditions. The Reactive Acid Tailings Stabilization (RATS) Task Force was initiated in to focus more exclusiv ely on acid drainage issues at hardrock mines in Canada.
Acid mine drainage (AMD), characterized by low pH and high concentrations of sulfate and heavy metals, is an important and widespread environmental problem related to the mining industry. Sulfate‐reducing passive bioreactors have received much attention lately.

Earth-Sci. Rev. v Google Scholar; MacQuarrie etal, Manganese nodules are an attractive source of base metals and critical and rare elements and are required to meet a high demand of today’s industry. In previous studies, it has been shown that high concentrations of reducing agent (Fe) in the system are beneficial for the rapid extraction of manganese.
However, it is necessary to optimize the operational parameters in order to maximize Mn. Based on the results obtained from a previous study investigating the dissolution of Mn from marine nodules with the use of sulfuric acid and foundry slag, a second series of experiments was carried out using tailings produced from slag flotation.
The proposed approach takes advantage of the Fe present in magnetite contained in these tailings and is believed to be cost-efficient. EPA B Region 8 Denver, CO. Region 9 San Francisco, CA: Region 10 Seattle, WA: August ABANDONED MINE SITE CHARACTERIZATION and CLEANUP HANDBOOK.

In theory, this technique could cleanse metal polluted soils by solubilizing contaminating metals, allowing them to be taken up by plants that would subsequently be removed from the site. We review the processes of metal solubilization, uptake by plants, and leaching during chelant-enhanced phytoextraction.
