  • Siderite

    It is a common mineral in sedimentary iron deposits or in metamorphic iron formations. Rarely as a primary magmatic mineral in carbonatites, syenites or pegmatites. Siderite is also rarely resent in some alpine type veins. In the hydrothermal veins, it is commonly associated with quartz, baryte, calcite and fluorite.

  • Iron Ore | The Canadian Encyclopedia

    Its most important mineral forms are magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe) and siderite (FeCO 3, 48.29% Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades between 30 and 44% Fe. Therefore, these mines crush and grind the ore, …

    The rock matrix minerals are quartz, siderite, calcite, and K-Al silicates. Gold is either disseminated in pyrite and arsenopyrite or appears as submicrometer to 100–150 μm particles in the primary sulfide ores. The gold mineralization is very unevenly distributed, with average grades reaching 9 g/t Au in economic ores.
