The complex legacy of arsenic contamination surrounding Giant Mine derives in large part from the roasting of arsenopyrite ore, a process that released approximately 20,000 tonnes of arsenic trioxide from the Giant roaster stack, and spread aerially to the surrounding environment, 86% of which occurred during the first 14 years of operations ...
Share It has been nearly two decades since Yellowknife's last gold mine closed. Sixty North Gold Mining is hoping to revive the industry. The junior mining company said it plans to soon restart mining for gold at Mon Mine, located about 45 kilometres north of Yellowknife.
A detailed characterization of arsenic solid and aqueous phases in lake waters, lake sediments and sediment porewaters as well as surrounding soils was conducted in three small lakes (<200ha) downwind and within 5 km of the historic mining and roasting operations of Giant Mine (Northwest Territories). These lakes are marked by differing ...
Remediating the mine, which is on Yellowknife's doorstep, involves freezing 237,000 tonnes of toxic arsenic trioxide dust a byproduct of the gold roasting process in chambers beneath the mine, alongside a range of other activities associated with cleaning the site to the highest standard possible.

The Giant Mine, located in Yellowknife, Northwest Territories, Canada has been operating as a gold mine since 1948. Giant has been primarily an underground operation which used roaster technology to remove of gold from refractory arsenopyrite ore. The roasting process produced arsenic trioxide bearing dust as a waste product. This dust was

Established at claims staked in 1935, the Giant mine site spans the west side of Yellowknife Bay, from the Yellowknife to the mouth of Back Bay. In the mid1940s, Government of Canada scientists determined that roasting ore from the site at high temperatures would be the most effective method for extracting gold from the Giant Canadian
Work will focus on permanently freezing 237,000 tonnes of toxic arsenic trioxide, produced during the gold roasting process, that was left underground when the mine closed. Freezing the ground around those underground chambers, while not considered an ideal solution, is the best option science is so far able to provide.
For a number of years, highly toxic arsenic trioxide a byproduct of the roasting process used to separate gold from the ore spread widely from the roaster, contaminating the land around the mine. Today, the majority of the arsenic, some 237,000 tones, is buried underground in frozen chambers.
The Giant Mine was a gold mine located on the Ingraham Trail, 5 km ( mi) north of Yellowknife, Northwest Territories. Giant Mine was within the Kam Group, a part of the Yellowknife greenstone belt.

Research conducted at the Giant Mine, a former gold mine in Yellowknife, NWT, Canada (Fig. 1) offered an opportunity to compare the geochemical behavior of As and Sb because both elements are elevated in mine waste and in the surrounding environment. Ore was roasted at Giant to extract gold, resulting in a complex range of solid As and Sb ...
We have evaluated roasting pretreatment of arsenicbearing ores in a broad context and related this to the specific operations at the Giant mine, Yellowknife, NWT, Canada, which roasted arsenopyrite (FeAsS)rich gold ore concentrates during 50 years of operations.
