The Bridgeville iron... - Mining Association of Nova Scotia | Facebook

The Bridgeville iron deposits in Pictou County were known as early as 1828 when ore from there was used in the new blast furnace erected at the Pictou Collieries of the General Mining Association. However, the transportation costs of hauling the ore to Pictou made the Bridgeville mine uneconomic and it shut down.

Direct reduced iron process - tec-science

The reduction of iron oxides takes place according to the following chemical equations: (1) F e 2 O 3 + 3 C O → 2 F e + 3 C O 2 (2) F e 2 O 3 + 3 H 2 → 2 F e + 3 H 2 O. In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted!
