Where to Find Mercury, Antimony and Arsenic in Canada
Where to Find Antimony Deposits. The principal ore of antimony is stibnite, Sb2S3, which is found in commercial quantities in veins, with a quartz gangue. Jamesonite, composed of lead, antimony, and sulphur, and bournonite, a copper-lead-antimony-sulphur mineral, may be commercially important for the antimony.

Arsenic removal is an important issue because arsenic contamination can cause considerable harm to ecosystems. In this study, modified polyacrylamide agents (BYYS) are introduced as environmentally friendly inhibitors for the selective separation of antimony–arsenic via low-alkalinity froth flotation.
Antimony and arsenic migration in a heterogeneous …
While antimony (Sb) and arsenic (As) co-contamination in subsurface soil systems due to the legacy of Sb smelting wastes has been documented, the role of inherent heterogeneity on pollutant migration is largely overlooked. Herein this study investigated Sb and As migration in a slag impacted, vertically stratified subsurface at an abandoned Sb smelter.
