Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...

While Britain had good iron ore reserves, the iron produced was of a low quality with plenty of impurities, limiting its use. There was plenty of demand, but not much was produced as wrought iron, which had many of the impurities hammered out, took a long time to make, and was available in cheaper imports from Scandinavia.
