Improvement of Low Mechanical Properties of Low Carbon …

Previous study revealed that low-grade laterite nickel ore, known as saprolite and limonite ore typically contains approximately 35–45% iron (Fe) and 0.8–1.5% nickel (Ni) for limonite and up to 18.9% Fe for saprolite . When this ore is processed or smelted into steel, the nickel content can be increased up to approximately 1–4%.

Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.
