Calcium lignosulphonate Could reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho (a tropical tree). Could use as a filler and binder in ceramic tiles, resins to fibre boards, casting sand and in fodder pellets. Could be used in lead batteries to acts on the crystallization of the lead sulfate thus increase the battery to get a much longer life-time.
