Key Difference: Iron is a chemical element that is found in abundance in the Earth''s crust. Steel is an alloy, meaning it is a mixture of two of more metallic elements or one metallic and nonmetallic element. Iron and steel are two substances that are often found in a variety of application such as utensils, construction, etc.
Jul 28, 2019· Nickel is primarily extracted from the nickel sulfides pentlandite, pyrrhotite, and millerite, which contain about 1% nickel content, and the ironcontaining lateritic ores limonite and garnierite, which contain about 4% nickel content. Nickel ores are mined in 23 countries, while nickel is smelted in 25 different countries.
Nickel is a silverywhite metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and Curie temperature is 355 °C (671 °F), meaning that bulk nickel is nonmagnetic above this temperature.
