    Properties of Iron

    Many minerals resemble ores, but do not yield the expected metal, and this was confusing when their chemical natures were not known. Cobalt was recognized by Brandt in 1735 and nickel by Cronstadt in 1750, but their compounds were not carefully studied until the next century. Properties of Iron

    Many people assume that magnetites name is derived from its magnetic properties, but the term magnet actually comes from the mineral. Magnetite was named after the Magnesia region of Thessaly, Greece, the home of the Magnetes and an important center of iron production.

    Q A Is gold magnetic? Department of Physics

    Oct 22, 2007Shawn Pure gold is not magnetic. That is, it doesnt form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit, but only so long as its in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold, for example gold with

    The Properties and Applications of Platinum

    Platinum metal has a number of useful properties, which explains its application in a wide range of industries. It is one of the densest metal elements almost twice as dense as lead and very stable, giving the metal excellent corrosion resistant properties. A good conductor of electricity, platinum is also malleable and ductile.

    Investigation of fractal properties of the magnetic survey

    Deposits with rich solid and brecciated ores, as a rule, are characterized by strongly inhomogeneous magnetic field, that are demonstrated by low values of the local singularity exponent. For ore occurrences and deposits of disseminated ores magnetic field has more smooth character, and values of the local singularity exponent are close to one.
