Iron ore - Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the.

The ancient art of smelting iron | Anita Chowdry

Jul 30, 2014 . Long before the development of industrial smelting processes, craftsmen set up small furnaces or Bloomeries to make useable iron or steel from natural local iron ores, such as Hematite, Siderite, or Magnetite. There has been a resurgence of interest in these processes as a kind of experimental archeology.

Goethite | mineral | Britannica

Jan 23, 2018 . In terms of relative abundance, goethite is second only to hematite (α-Fe2O3) among iron oxides. Goethite is normally formed under oxidizing conditions as a weathering product of iron minerals (e.g., pyrite, magnetite). Because it is formed near the surface, goethite is the major component of the gossan of.

general features of the magnetite ores of western north carolina and .

brown hematite, magnetite, and titaniferous magnetite ores have been mined and smelted, but in later years the titaniferous ores have been completely neglected because they are not adapted to modern blast-furnace practice. Until within a few years the magnetite de- posits furnished nearly all the ore mined, but recently.

Hematite - Sandatlas

Hematite (Fe2O3) is an iron oxide mineral. It is widespread in nature, especially in sedimentary environments. Hematite is one of the two principal iron ores. The other is magnetite, which is also an iron oxide mineral. The term 'hematite' itself might not be familiar to everyone, but its rusty red color definitely is. Sandstones.
