|The Physical Object|
The total sulphide sulphur concentration was on average % for the pyritic tailings, % for the magnesite tailings and % for the current tailings. According to Räisänen (), the oldest tailings are acid generating whereas the magnesite tailings have excellent buffering capacity and are non acid generating (Räisänen & Juntunen ). This report summarizes data obtained from field sampling of mine tailings, wasterock, sediment, water, and biota at the Little Bonanza Mine that was completed on April 6, Conditions during sampling were dry and no rain had occurred in the watershed for several weeks. Our results permit a preliminary assessment of the mining sources of Hg. Sulphidic mine tailings are among the largest mining wastes on Earth and are prone to produce acid mine drainage (AMD). The formation of AMD is a sequence of complex biogeochemical and mineral dissolution processes. It can be classified in three main steps occurring from the operational phase of a tailings impoundment until the final appearance of AMD after Cited by:

Outcrop test results indicated that the sulphide minerals in the Mt. Milligan deposits were not reactive and had very slow reaction rates when compared to the oxidation rates experienced at sites which have acid drainage problems.

As the sulfide minerals are depleted, the front migrates deeper into the tailings, where fresh sulfide mineral Field sampling manual for reactive sulphide tailings book are available for oxidation.
Detecting the oxidation front is relatively simple in the field, because it is marked by a sharp decline in the O 2(g) concentration at the sulfide oxidation front (Blowes and Jambor, ).Cited by: Sampling Procedures Handbook, USEPA RCRA Groundwater Monitoring Technical Enforcement Guidance Document, etc.).

A series of samples were sent to International Plasma Labs and analyzed using 1 0/20/20/60g-aqR Au Te S9T) by. Field measurements were performed at the abandoned Manitou tailings disposal site in TSF 2 to assess the ability of the EWT and monolayer cover technique to control the oxygen flux into the reactive tailings.
Field data indicate that the degree of saturation at the base of the fine-grained cover remained high because of capillarity rise effects Cited by: 1.
This lump value can be used to evaluate the steady-state oxygen flux entering the exposed sulphide tailings. In this paper, a numerical parametric study is performed to investigate the effect of test duration and headspace height, h, on results obtained from OC tests. The assessment also considers tailings with different values of D e and K r Cited by: advective flow field have not yet been fully implemented.
Nevertheless, the results provide a useful sensitivity study of material properties and parameters in the near-field and provide first order estimates of sulphide fluxes and canister corrosion rates.

The non-sulphide copper analysis (i.e. a % sulphuric acid leach) indicated that up to 66% of the solid phase copper in the tailings materials is associated with the non-sulphide portion of the tailings.
As extremely acidic conditions are required to leach this form of copper, it is considered. A versatile numerical model that couples oxygen diffusion and sulfide‐mineral oxidation (PYROX) has been developed to simulate the oxidation of pyrite in the vadose zone of mine tailings.
A shrinking‐core oxidation model and a finite element numerical scheme are used to simulate the transport of oxygen and oxidation of pyrite by: Where a rotary drilling machine is not possible to place, samples were collected with an Eijkelkamp soil core manual sampler.
Sampling was sequential with a centimeter vertical constant spacing and lower in depth than boreholes. This is the case of tailings studied at the Iberian Pyrite Belt district.

Numerical simulations, using reactive transport code MIN3P, correctly reproduced the San Manuel field and analytical results when the sulphide reactivity was controlled by reducing the effective sulphide mass within the numerical models from.
Weathering of sulfide tailings. Tailings weathering begins with the oxidative dissolution of pyrite-rich wastes and the release of sulfate (SO 4 2−), metals (Fe 2+), and protons (H +) to solution (Nordstrom and Alpers, ).Production of Fe 2+ and H + further promotes surface reaction and dissolution of pyrite and gangue (e.g., carbonate and silicate) minerals, Cited by: In tailings, the AP next to the disposal location may be higher than predicted from the analysis of tailings leaving the processing plant due to preferential deposition of the heavy sulphide minerals on the tailings beach.
