Heat transfer during acid mine drainage production in a waste rock dump, la mine Doyon (Quebec)
by Canada Centre for Mineral and Energy Technology = Centre canadien de la technologie des minéraux et de l"énergie in Ottawa, Ont
Written in English
The monitoring program used to determine the physical and geochemical conditons which prevail during acid mine drainage production at La Mine Doyon, Quebec, was described. The mechanisms which contribute to the production of acid mine drainage and the mechanisms which affect heat transfer within the waste dumps were examined. The cyclic variations of temperature in waste rock dumps were interpreted, and heat production rates were evaluated to allow for the derivation of pyrite oxidation rates.

Sulphides are important from an environmental perspective because, in the presence of water and oxygen, they can oxidize to create sulphuric acid, a process commonly known as acidic drainage and also known as acid mine drainage or acid rock drainage. The result is the generation of metal-laden effluents of low pH. Acidic drainage can have very. This book provides a timely review of strategies for coping with polluted ecosystems by employing bacteria, fungi and algae. It presents the vast variety of microbial technologies currently applied in the bioremediation of a variety of anthropogenic toxic chemicals, .
occurs when sulfur compounds in mine waste are exposed to air, oxidize, and dissolve in rainwater to form a sulfuric acid solution. Divergent Plate Boundary This is a plate boundary where two oceanic plates are separating, and molten rock flows up into the void that is .

Commonly referred to as acid rock drainage (ARD) or acid mine drainage (AMD), acid drainage may be generated from mine waste rock or tailings (i.e., ARD) or mine structures, such as pits and underground workings (i.e., AMD). Acid generation can occur rapidly, or it may take years or decades to appear and reach its full potential. Toxic residue is different from the major harmful effect, the acid rock runoff from otherwise ordinary rock. From your link "A special feature of the waste rock is that some of it contains sulphide and is capable of producing acid drainage when exposed to oxygen and water. This rock is referred to as potentially acid forming (PAF) rock.

HEAT TRANSFER DURING ACID MINE DRAINAGE PRODUCTION IN A WASTE ROCK DUMP, LA MINE DOYON (QUÉBEC) MEND Report c This work was done on behalf of MEND and sponsored by Cambior Incorporated, Lac Minerals, and the Province of Québec and the Canada Centre for Mineral and Energy Technology (CANMET) through the CANADA/Québec Mineral Development.

Acid mine drainage (AMD) resulting from pyrite oxidation is produced in two large waste rock dumps at La Mine Doyon located in Northwestern Quebec.
A monitoring program for the South Dump is designed to characterize the physical and geochemical conditions prevailing during AMD production within this coarse unsaturated material. Waste rock piles producing acid mine drainage (AMD) are complex and heterogeneous unsaturated systems in which multiple coupled processes are involved: multiphase flow of fluids (liquid and gas.

Such modelling was used to evaluate the effects of closing options for a waste rock pile, including resloping and the placement of a cover, on AMD production from the South Dump of the Doyon Mine (Quebec, Canada).
The thermal data recorded within the pile during 15 years show a steady reduction of temperature over the last 10 years. [LGI] R. Lefebvre, P. Gelinas and D. Isabel, Heat transfer during acid mine drainage production in a waste rock dump, La Mine Doyon (Quebec), MEND Report [Low] Richard T.

Saline-sodic shale overburden associated with oil sand mining is a potential source of salt release to surface water and groundwater and can lead to salinization and/or sodification of reclamation covers.
Weathering of shale overburden due to oxidation of sulphide minerals within the shale leads to sulphate (SO4 2−) production and increased salinity. Physical and geochemical heterogeneities in mine waste rock complicate the prediction and assessment of waste rock effluent water quantity and quality.
The objective of this research is to provide a holistic conceptual understanding of the hydrological and geochemical processes that control effluent water quantity and quality, and the complex interactions among processes at the field scale. The effective control and treatment of acid mine drainage (AMD) from sulfide-containing mine wastes is of fundamental importance for current and future long-term sustainable and cost-effective mining industry operations, and for sustainable management of legacy AMD sites.
Historically, AMD management has focused on the use of expensive neutralising chemicals to treat toxic leachates. Multiphase transfer processes in waste rock piles producing acid mine drainage: 1: Conceptual model and system characterization.
Neutron radiography and other NDE tests of main rotor helicopter blades, (). Waste rock piles producing acid mine drainage (AMD) are complex and heterogeneous unsaturated systems in which multiple coupled processes are involved: multiphase flow of fluids (liquid and gas), heat transfer and mass transport.
Numerical modelling is required to consider together these processes. Such modelling was used to evaluate the effects of closing options for a waste rock pile.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the s, has been widely used to generate electricity.
Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and.
Mine site rehabilitation and mine waste science are examples of newly emerging disciplines. This book has arisen out of teaching mine waste science to undergraduate and graduate science students and the frustration at having no appropriate text which documents the scienti?c fundamentals of such wastes.

An acid stream with pH between – and 50– mg/L of arsenic flowed into the Amous river, with a very high environmental impact. On the other hand, in Giant mine (Canada),tons of arsenic trioxide dust is currently safe, but when the rock at Giant Mine was crushed and mined out, the arsenic was exposed to the environment.Full text of "Mine drainage and surface mine reclamation: proceedings of a conference" See other formats.
