The Pamphlet Collection of Sir Robert Stout: Volume 2

No. 218

No. 218.

This speciman is hydrated sesquioxide of iron from Port Molyneux. It yielded:—
Water 14 per cent.
Oxide of iron 65.5 per cent.
Earthy matter (clay silica) 20.5 per cent.

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.
