Nevertheless, sedimentary rocks in which the proportion of iron exceeds 15 percent are separately categorized as iron-rich. Two major types of iron-rich sedimentary ...

Hematite is harder than pure iron, but it is much more brittle. The name hematite is derived from the Greek word haimatites for blood. It is mined in Australia, Brazil (rainbow variety), England, Mexico, the United States and Canada. It is the state mineral of Alabama, USA where approximately 375 million tons were mined between l840 and 1975.

Iron ore deposits in Missouri are divided into three main types: Precambrian-hosted hematite and magnetite, filled-sink hematite and limonite or brown iron ore deposits. Hematite (Fe 2 O 3) ... Hematite is named from the Greek for "blood stone" due to its red color when powdered. Magnetite. Chemical composition: Fe 3 O 4, or iron oxide.

2. Natural/Native metals. Ores and native metals- Naturally formed metals in rocks or may be the metal itself like Michigan copper, gold, silver. Michigan copper float. There are also many hot rocks that can also cause a metal detector to go off! A hot rock is any rock or stone that contains a valuable mineral such as copper, gold, or silver.

Hematite is a rich source of iron and has been used for several purposes, ranging from decoration to embellishment. It is a solid mineral substance, which is a rich source of iron. An important ore of iron (present in the form of ferric oxide), it is composed of two molecules of iron and three molecules of oxygen.

Hematite. Hematite (American English) or haematite (British English) is a common mineral that is mined as the principal ore of iron.
