The characterization, persistence, and bioaccessibility of roaster-derived arsenic in surface soils at Giant Mine, Yellowknife, NT
Approximately 20,000 tonnes of arsenic (As)-bearing emissions from roasting arsenopyrite ore were aerially released from 1949-1999 at Giant Mine, located outside Yellowknife, NT. As part of the process used to free ...
Speciation and mobility of Antimony and Arsenic in mine waste and the aqueous environment in the region of the Giant mine, Yellowknife, Canada
Antimony is a potential human and ecosystem health risk, yet large gaps in the existing knowledge of the geochemical behaviour of Sb persist. At the Giant mine, an abandoned gold mine about to undergo remediation, Sb is ...
The influence of bacteria on the stability, speciation and mobility of arsenic in contaminated sediments at Terra mine, N.W.T., Canada
Terra mine is an abandoned copper and silver mine in the Northwest Territories, Canada, from which mine tailings were deposited into Ho-Hum Lake, adjacent to the mine’s processing plant. The tailings contain elevated levels ...
EFFECT OF TAILINGS MINERALOGY AND INFILTRATION WATER CHEMISTRY ON ARSENIC RELEASE FROM HISTORIC GOLD MINE TAILINGS
The existence of small-scale gold mining in Nova Scotia between 1868 and 1942 has resulted in many high arsenic (As) tailings areas in the province, some of which are near rural/urban areas and are used for recreational ...
ARSENIC MOBILITY AND ATTENUATION IN A NATURAL WETLAND AT TERRA MINE, NORTHWEST TERRITORIES, CANADA
Elevated arsenic (As) concentrations in surface water from storing mine tailings in lakes can have a negative impact on local and downstream vegetation and aquatic life. At Terra Mine, an abandoned silver and copper mine ...
