Abstract The development of reagent strategies for the flotation of boron minerals requires an understanding of flotation chemistry of reagent/mineral interactions. The floatability of a typical boron mineral, colemanite, was investigated in a microflotation cell by using anionic and cationic surfactants as collectors and tannic acid as a depressant.

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.

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

Flotation Chemistry of Boron Minerals Semantic Scholar

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 ...
