List Sulphide Minerals - Mineral Processing & Metallurgy

The proportion of iron is 100 — (34.8 + 34.8) = 30.4%. Roughly, the ore may be considered as composed of one-third each of copper, sulphur, and iron. This is the commonest ore of copper; but its value depends so much on circumstances other than the percentage of copper contained in it that it is not quoted on the market.

Nickel | Geoscience Australia

Most mined nickel derives from two types of ore deposits that form in very different geological environments: magmatic sulfide deposits, where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8], and laterites, where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate). Magmatic ...

What are the differences between iron and nickel? | Yahoo ...

Feb 09, 2011· Iron and Nickel share relatively close atomic weights and they have the same Mohs hardness. Nickel appears to be 13% more dense than iron, but iron has a melting point that is 150 degrees F higher than nickel. Aside for abundance, what are the differences? How do they compare in terms of conducting electricity, resisting breakdown from thermal energy, and interacting with other …

The Mohs Scale of Hardness for Metals: Why It Is Important

The Mohs scale of hardness can be useful when you are shopping and debating between pieces of jewelry made from different metals. By looking them up in the metals hardness table, you can see which option will give you better durability, and you can then decide if the price asked for it is worth it to you.

science based - This sword is forged from meteorite iron ...

Metallic meteorites are made of iron nickel alloys. Iron has been made from terrestrial ores for a few thousand years but nickel is pretty hard to get. We didn't isolate it here until the 1750s. Meteoric iron has average 10% nickel but can be 25% or more in some cases. Cobalt is …

Nickel - Wikipedia

Type 2 telluric iron also contains around 0.05 to 4% nickel, but typically less than 0.7% carbon. Type 2 is a malleable nickel-iron which responds well to cold working. The carbon and nickel content have a great effect on the final hardness of the cold-worked piece. Type 2 is found as small grains mixed within basalt rock. The grains are ...

Iron-Nickel: The meteorite mineral Iron-Nickel information ...

Terrestrial Iron-nickel is very rare. Iron-nickel Meteorites are also rare, but are far more common than terrestrial Iron-nickel. Because there is an abundance of iron and nickel compounds, Iron-nickel is not used as an ore of either iron or nickel. Iron-nickel in all forms is valued as a rare collectors item, and meteorites are especially popular among collectors.

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
