It is clear the Pre-Float stage creates much looses in Cu, Au and Ag. Mineralogy work on this stream would help understand why the metals are naturally floatable using only MIBC. Knowing the cause of this floatability (chemical, physical or mechanical) would open the opportunity to implement solutions that would increase Cu, Au and Ag Recoveries by reducing their losses to pre-flotation.
