There are a number of blast furnaces in Canada, among them being those of the Dominion Iron & Steel Co., Sydney; the Nova Scotia Steel & Coal Co., Sydney Mines, and the Londonderry Iron & Mining Co., Londonderry, all of which use ores from Newfoundland and Nova Scotia; the Algoma Steel Corporation, Sault Ste. Marie, Ontario; the Steel Company of Canada, Hamilton, Ontario; the Canadian Furnace Co., Port Colborne, Ontario; the Canada Iron Foundries, Midland, Ontario; the Standard Iron Co., Deseronto and Parry Sound, Ontario; and the Atikokan Iron Co., Port Arthur, Ontario, which use largely Lake ores of the United States and Canada. The Moose Mountain Co., of Sellwood, Ontario, has a magnetic concentrating and briquetting plant using ore from the Moose Mountain mine. In May, 1920, the British Empire Steel Corporation, the second largest in the world, was formed by the merger of nine steel, coal, ship-building and transportation companies. In 1912 Canada produced 156,000 tons of iron ore, and made 906,000 tons of pig iron.[41] In 1918 she made 1,066,071 tons of pig iron. The iron mines of Canada are largely of Canadian and partly of American ownership.

The principal producing area is that of Tayeh, south of Yangtse River in the Province of Hupeh, where a series of ore bodies, consisting of mixed hematite and magnetite, occurs along the contact of limestone and intrusive syenite. The deposits are estimated to contain about 40 million tons of ore.[42] The Han-Yeh-Ping Iron & Steel Co., largely controlled in Japan, owns these deposits and the Han Yang steel plant near Hankow. Iron ore similar to that of Tayeh is reported to occur farther down the Yangtse at Tungling, in the Province of Ngan-whei, and also along the coast near Amoy, Province of Fukien. The deposits near Amoy are said to contain about 25 million tons. [42] BAIN, H. F.: “Notes on Iron-Ore Resources of China,” _Trans._ Am. Inst. Min. Eng., 1918. Of considerable importance are the mixed hematite and magnetite ores of Chin-ling-chen, near Kiaochow, Shantung Province. A series of ore bodies, some of them 100 feet in width, are said to occur along a contact zone two kilometers in length.[43] The deposits were exploited by Germans and are being developed by Japanese.

Bedded siderite ores similar to the Coal Measures ores of England have been mined for many years in Shan-si Province and smelted in native furnaces. In Hunan Province, also, this type of ore is mined.
