Technology of production of the pyrite cinders of Mo middlings includes granulation, firing to oxidize sulfide minerals and to recover Re-oxide. If kaolin is used a dilution of the pyrite cinders with Mo takes place. The research is devoted to the development of alternative to kaolin organic binding agents. The approach is based on a comparison of hydrophilic, strength & technological characteristics of pellets. The new batch was developed differing from the traditional mixture with organic additive burning to the ground and minimizing Mo dilution, maximizing Re, Au, Ag hydrometallurgical recovery.
