Guide for iron ore dressing - Mining-pedia

Generally, iron ore with a grade of less than 50% needs to go through a dressing process before it can be sent to smelting for utilization. After the mined ore goes through the processes of crushing and grinding, magnetic separation, flotation and gravity separation, the high-grade concentrate is obtained.At present, the iron ore resources are decreasing day by day.

Siderite - Wikipedia

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.

Iron Ores Article about Iron Ores by The Free Dictionary

The ore minerals in silicate iron ores are iron chlorites, usually accompanied by hydrous ferric oxides, and sometimes by siderite (25–40 percent iron). There is a negligible content of sulfur and up to 0.9–1.0 percent phosphorus. Silicate ores form beds and lenses in friable sedimentary rocks. They often have an oolitic texture. In the crust of weathering they are converted into bog iron ...
