Port Molyneux
Port Molyneux.
This specimen is hydrated sesquoxide of iron from Port Moly neux. It yielded:—
This is equal to 46 per cent. of metallic iron. If there is a large quantity of this ore near a good coal field, it should take a good place among the industries of the future. The small quantity of silica present (about 10 per cent.) will not require much lime for its removal.
Water | 14 per cent. |
Oxide of Iron | 65.5 per cent. |
Earthy matter (clay silica) | 20.5 per cent. |
