yellow streak which easily distinguishes it from hematite. It also contains water of crystallization and is often associated with other iron ores which are hydrous. This is the most abundant form of iron ore in Indiana. It occurs as concretions in soils, which are

Siderite is also the name of a type of iron meteorite.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

Character of Pig-iron.—Ores suitable for "gun-metal" should be reduced in the smelting-furnace, with charcoal and the warm blast, varying from 125 to 300 Fahr., depending upon the ore used. Iron thus made, or pig-iron, should be soft, yielding easily to the file and chisel; the appearance of the fracture should be uniform, with a brilliant aspect, dark gray color, and medium-sized crystals.

Iron ore's near 10 percent rebound on Thursday following a horror streak this week left strategists debating whether more pain is in store for the beleaguered commodity.

Iron - Iron - Compounds: The most important oxidation states of iron are +2 and +3, though a number of +4 and +6 states are known. For the element iron the trends in the relative stabilities of oxidation states among elements of the first transition series are continued, except that there is no compound or chemically important circumstance in which the oxidation state of iron is equal to the

What is meant by a streak of mineral/ore?

The streak of a mineral is the colour of a fine powder of that mineral. The usual method of determining streak is by scratching the mineral on an unglazed white ceramic plate (eg the back of a tile). This, of course, only works for minerals that a
