 · Lumps of iron slag from smelting processes can also have some similarities to meteorites so it is important to be careful. The major difference between iron produced by human activity and meteoritic iron is the presence of the element nickel. Iron metal in all meteorites contains at least some nickel whereas man-made metal objects generally do

Nickel smelting producing-Metalpedia

The principle nickel sulphide is pentlandite (NiFeS2) which is usually associated with chalcopyrite and iron sulphides. International Nickel (INCO) and Sherritt Gordon use a bulk Cu/Ni float pictured below followed by selective flotation of the two elements into separate concentrates. Other Canadian producers leave separation to the smelters.

Fe-55Ni welding elec-trodes are used to make weld deposits that can hold in solid solution many of the alloying ele-ments common to cast iron. Furthermore weld deposits made with Fe-55Ni welding consum-ables have an acceptable thermal expansion match to the cast iron.

Ferronickelan overview ScienceDirect Topics

A high-carbon product tends to be produced by smelters that smelt calcine that is rich in nickel and low in iron (Warner et al. 2006). It is the product of strongly reducing conditions in the smelting furnace. Strongly reducing conditions give recoveries of nickel as high as 98 into the ferronickel.

NickelElement information properties and uses

Meteorites contain both iron and nickel and earlier ages used them as a superior form of iron. Because the metal did not rust it was regarded by the natives of Peru as a kind of silver. A zinc-nickel alloy called pai-t ung (white copper) was in use in China as long ago as 200 BC. Some even reached Europe.

Nickel Metal It s Properties History Production Uses

 · Pure nickel reacts with oxygen and therefore is seldom found on the earth s surface despite being the fifth most abundant element on (and in) our planet. In combination with iron nickel is extremely stable which explains both its occurrence in iron-containing ores and its effective use in combination with iron to make stainless steel.

Nickel alloys can be joined reliably by all types of welding processes or methods with the exception of forge welding and oxyacetylene welding. The most widely employed processes for welding the non-age-hardenable (solid-solution-strengthened) wrought nickel alloys are gas-tungsten arc welding (GTAW) gas-metal arc welding (GMAW) and shielded metal arc welding (SMAW).

 · Crucibles are lined with refractory materials. Steel processing makes use of graphite or a combination of chromite and magnesite for direct contact with the melt. Cast iron processing often uses engineered clays also known as alumina-magnesia-silica mixtures. Graphite is harder to form than clay-type refractories.

Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace. The limestone combines with the rock and other impurities in the ore to form a slag which is lighter than the iron and floats on top. As the volume of the charge is reduced more is continually added at the top of the furnace.
