The Canadian deposits of chromite, or chrome iron ore, occur in the serpentine belt of the eastern townships of the province of Quebec. It is only within comparatively recent years that these deposits have been worked. The centre of production is Black Lake, in the township of Coleraine, on the line of the Quebec Central Railway. The annual production of chromite of this district is in the vicinity of 9,000 tons, containing a minimum of forty five percent. of chromic sesquioxide, this percentage constituting the standard.
