    Boron Wikipedia

    Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring

    Equivalent carbon content Wikipedia

    The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron-carbon phases are better understood than other iron-alloy

    Boron minerals exhibit an array of solubilities depending upon the cations in the lattice structure. A classification of semisoluble (colemanite and ulexite) and soluble salts (borax) may be appropriate as each group of minerals behaves differently in flotation. While borax has to be concentrated from its saturated brine, colemanite can be recovered by conventional flotation as other

    The beneficiation of boron minerals by flotation with well defined systems has been only slightly investigated in the literature. The difficulty arises from the fact that boron minerals cover a spectrum of solubilities. Colemanite (a calcium-containing, relatively insoluble, boron mineral) and borax (a highly soluble boron mineral) have been used to exemplify the flotation of boron minerals.
