Blasts designed for in situ copper leaching must produce adequate fragmentation and permeability for successful leaching. Copper recovery depends to a large extent on the particle size distribution created by the blast, the permeability in the blastfractured zone, and the ability to maintain solution flow with a minimum amount of channeling.
