بيت /which has higher iron content hematite magnetite siderite
They are found mainly in the crust of weathering (oxidation zone) of ferruginous quartzites and skarns of magnetite ores. Such ores are often called martite ores (martite is a pseudomorphosis of hematite after magnetite). The average iron content is 51–60 percent, sometimes higher, with insignificant admixtures of sulfur and phosphorus.
