Accelerated autocondensation of quebracho tannin wood adhesive by boric acid
, 2015 Quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. In this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood.

Effects of Quebracho Tannin on Recovery of Colloidal Gold from Bioleached Wash Liquor
Ghana Mining Journal, 2015 Gold occurs in some concessions as submicron particles in pyrite and arsenopyrite, which is processed in a flotation concentration to obtain gold enriched sulphide concentrate. The concentrate is then treated in a biological oxidation step to oxidize the sulphides, liberate the occluded gold and make them amenable for cyanidation. The oxidized sulphide

Polyethylene glycol influences selection of foraging location by sheep consuming quebracho tannin.
Journal of animal science, 2002 Tannins are a heterogeneous group of phenolic polymers that can induce detrimental effects when consumed by herbivores. Polyethylene glycol (PEG) binds to tannins and thus attenuates their negative effects. Our objective was to determine whether sheep actively seek PEG when fed tannins and thus modify their foraging location as a function of the ...
