2009-4-7  They were fed by iron deposits at Trois-Rivières and operated from 1738 to 1883. Industrial demand for coal and iron spurred the expansion of mining and smelting in the late colonial period. Coal mining developed rapidly near Sydney, Cape Breton, and, in the mid-19 th century, major coal deposits were located on Vancouver Island.

How Is Iron Extracted From the Earth? Reference

2020-3-26  Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
