Overview

Excerpt from Phosphate in Canada Between 1883 and 1891, phosphate mining was an important industry in Canada, the average annual output of apatite being about tons. This amount appears comparatively trivial at the present time, when the world's total annual production is figured in millions of tons; but at the period mentioned the Canadian output constituted quite an important proportion of the total supply. While the discovery in more recent years of enormous deposits of sedi mentary phosphate in various parts of the world has reduced the Canadian apatite bodies to a position of relative unimportance, and has brought about an almost complete cessation of mining, owing to the cheapness with which the bedded deposits can be worked, Canada yet possesses quite material reserves of apatite. At the present time few uses are known for this mineral that cannot be met almost as well by the cheaper, sedimentary phosphate, and consequently the demand for it is small.
