Problem of Cargo Liquefaction in the Maritime Industry

    Aug 08, 2019 · The understanding of the nature of liquefaction as well as microscopic and macroscopic behavior of the material when liquefied, led us to identify the critical parameters that cause cargo liquefaction. The cargoes which are more susceptible to liquefaction are iron ore fines and nickel ore even though any granular cargo may liquefy.

    Optimal feed grade for iron ore concentrates is usually in excess of 60% Fe by weight, with less than 0.20% P, 3-7% silica, less than 5% Al, and low S and Ti. The inclusion of even small amounts of some trace elements can have profound effects, both good and bad, on the behavior of iron in a blast furnace.

    Isotopes of iron - Wikipedia

    Iron-60. Iron-60 is an iron isotope with a half-life of 2.6 million years, but was thought until 2009 to have a half-life of 1.5 million years. It undergoes beta decay to cobalt-60, which then decays with a half-life of about 5 years to stable nickel-60. Traces of iron-60 have been found in lunar samples.
