Applied Geochemistry, 2013
Abstract During mining operations, explosives are used to fragment rock into workable size fractions. Mine-water chemistry can be affected by blasting agent residuals, including NH3, NO 2 - , NO 3 - , Cl−, and ClO 4 - .

The Diavik waste rock project: Initial geochemical response from a low sulfide waste rock pile
Applied Geochemistry, 2013Abstract Three large-scale experimental waste rock piles (test piles) were constructed and instrumented at the Diavik Diamond Mine in the Northwest Territories, Canada, as part of an integrated field and laboratory study to measure and compare physical and geochemical characteristics of experimental, low sulfide waste rock piles at various scales ...

The Diavik waste rock project: Water flow through mine waste rock in a permafrost terrain
Applied Geochemistry, 2013Abstract A field experiment is being carried out at the Diavik diamond mine in northern Canada to investigate the influence of unsaturated flow behavior on the quality of drainage from mine waste rock piles in a region of continuous permafrost. This paper is part of a series describing processes affecting the weathering of waste rock and transport of

Chemical precipitation within pyritic waste rock
Hydrometallurgy, 2005Abstract Pyritic waste rock piles generate acid rock drainage (ARD). If the chemical precipitation of metals could be induced within waste rock piles by the weathering products of phosphate and carbonate minerals, seepage metal loads–and treatment costs–could be reduced.

Diavik waste rock project : thermal transport in a covered waste rock test pile
2011Covers are widely used in the management of mine tailings and waste rock and most current cover designs and constructions are in temperate regions. However in cold regions, certain features and processes are unique and they can be utilized to reduce the production of acid rock drainage (ARD).

Waste Rock and Tailings Mixtures as a Possible Seal for Potentially Acid Forming Waste Rock
2003Potentially acid forming (PAF) waste rock contained in dumps formed as a result of open cut mining of metalliferous orebodies are conventionally sealed or covered using a near-saturated, low permeability compacted clay layer, protected with a mulch layer and/or vegetated growth medium.

Strategy for Radioactive Waste Disposal in Crystalline Rocks
Science, 1981A strategy for waste disposal is proposed in which the repository would be situated in a crystalline rock mass beneath a blanket of sedimentary rocks whose ground-water flow characteristics are well understood. Such an approach exemplifies the concept of multiple barriers to the isolation of radioactive wastes from the biosphere.

Plant growth in amended molybdenum mine waste rock
Environmental Science and Pollution Research, 2017This greenhouse study examined the use of organic and inorganic soil amendments in waste rock material from the former Questa Molybdenum Mine in northern New Mexico to promote beneficial soil properties. Waste rock material was amended with 11 soil amendment treatments that included municipal composted biosolids, Biosol®, inorganic fertilizer, and two ...

Applied Geochemistry, 2013
Three large-scale instrumented waste rock piles were constructed at the Diavik Diamond Mine in the Northwest Territories, Canada. These experimental waste rock piles (test piles) are 15 m high and are part of an integrated field and laboratory research program to characterize and compare low-sulfide waste rock and drainage at various scales.

Applied Geochemistry, 2013
The physicochemical processes that affect acid mine drainage (AMD) in unsaturated waste rock piles and the capabilities of small-scale laboratory experiments to predict AMD from waste rock are not well understood. An integrated laboratory and field study to measure and compare low sulfide waste rock and drainage characteristics at various scales has ...
