METHOD FOR RECOVERING ABRASIVE ELEMENTS CONTAINED IN A RESIN-BONDED MATERIAL AND USE OF SAID ELEMENTS THUS RECOVERED
A process for recovery of all or some abrasive elements contained in an abrasive material in which the abrasive elements are dispersed in a resin with at least one phenolic hydroxyl group, the process including steps of: a) bringing the abrasive material into contact with an aqueous nitric solution (S1), whereby an aqueous nitric solution (S2) is obtained containing abrasive elements and residue derived from degradation of the resin; then (b) separating the abrasive elements from the aqueous nitric solution (S2) obtained after step (a). The use of abrasive elements thus recovered particularly to prepare agglomerated abrasives or coated abrasives.
