Iron ore - Wikipedia
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Pig iron - Wikipedia
Pig iron is an intermediate product of the iron industry, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

Ironstone - an overview | ScienceDirect Topics
Blackband ironstones are, typically, fossiliferous sapropel-rich (usually with an organic content in excess of 10%) finely laminated sideritic ironstones. Although non-laminated types are known, more frequently they are formed of alternating siderite- and organic-rich laminae. They are found almost exclusively above coal seams in a lacustrine parasequence with mudstone and seat earth deposits ...
Copper Ore to High-Purity Copper, and the …
To obtain high-purity copper, the ore is concentrated for processing by crushing and grinding it into a powder containing 20-30% copper. The concentrates are smelted and the sulfide minerals are partially oxidized to yield a layer of “matte”, a mix of copper-iron sulfide and slag, and an upper layer of waste.

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required.
