Some ore deposit types, such as volcanogenic massive sulphide deposits, can contain both syngenetic and epigenetic mineralization. |
The kind of ore that attracted iron was once called magnesian stone, because it was discovered in the part of Asia Minor near Magnesia. |
With Finex, coal and ore are turned into iron without coking and sintering. |
The Mesabi Iron Range contains some 110 miles of small towns built at the turn of the last century along a seam of iron ore called taconite. |
The traditional method for extracting pure iron from its ore is to heat the ore in a blast furnace with limestone and coke. |
The remnant ore inside the old stopes, pillars and tailings used as backfilling are being leached with mild acid solution. |
