Siderite Wikipedia

Although spathic (carbonate) iron ores, such as siderite, have been economically important for steel production, they are far from ideal as an ore. Their hydrothermal mineralisation tends to form them as small ore lenses, often following steeply dipping bedding planes. This makes them not amenable to opencast working, and increases the cost of working them by mining with horizontal stopes. As the individual ore bodies are small, it may also be necessary t
