Iron processing | Britannica

Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower. Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66.

Hematite and Itabirite - Sundance Resources Limited

Hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as “Direct Shipping Ore” or “DSO” because it is mined and beneficiated using a relatively simple crushing and screening process before being exported for use in steel mills. Hematite is often cheaper to.

Ore - Wikipedia

The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the.
