  • Tannic acid Wikipedia

    Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity (pK a around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C 76 H 52 O 46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the number of galloyl

    The fluorite ore contains about 85% CaF 2,and fluorite is mainly associated with quartz and calcite. In order to meet fluorite market, the gangues have to be removed to produce a high-grade fluorite concentrate of 97% CaF 2,which is actually realized in the plant by froth flotation using oleic acid as collector and quebracho as depressant. The flotation circuit consists of rougher flotation and two-step cleaner flotation

    The flotation recoveries of molybdenite and chalcopyrite were depressed in the presence of these organic matters, with humic acid being the stronger depressant followed by tannic acid and fulvic acid. These flotation results are well explained by the amount of organic matters adsorbed on the two minerals with more adsorption of humic acid than tannic acid and fulvic acid. These acids, which
