The traditional method for extracting pure iron from its ore is to heat the ore in a blast furnace with limestone and coke. |
Some ore deposit types, such as volcanogenic massive sulphide deposits, can contain both syngenetic and epigenetic mineralization. |
The remnant ore inside the old stopes, pillars and tailings used as backfilling are being leached with mild acid solution. |
At the nearby Lady Tennyson small amounts of copper ore averaging twenty-five to thirty percent were also raised. |
Indeed, the large bulk shipping carriers are queued up for weeks waiting to load basic ore and other items on the way to China. |
The kind of ore that attracted iron was once called magnesian stone, because it was discovered in the part of Asia Minor near Magnesia. |
