ABSTRACT:
Agglomerating agent and method for use in heap leaching of mineral bearing ores. Cationic polymers alone or in combination with cement or lime are highly effective agglomerating agents in acidic or alkaline leaching operations. The cationic polymers are preferably graft copolymers, block copolymers or linear copolymers of acrylamide and diallyl dimethyl ammonium chloride.
