re: more thought for the sulphides bonanza ahead Westmoon,

The copper,lead, zinc, silver deposit is one of the more common mineral associations around. Anyone who produces from a primary copper sulphide deposit has to remove contaminants along the way, in this particular case you get paid for the "contaminants" much better than removing annoying things like iron sulphides.

The process goes like this:
Crush
Grind
Add Depressant for zinc sulphide
Flot the copper and lead concentrate
Add activator for zinc
Flot zinc concentrate
Separate copper and lead concentrate via flotation.
Get paid. Receive silver credits in varying amounts for different concentrates.
