Finally some good news - but more complete gibberish to prove that the MD doesn't have the slightest clue about the process plant - "Specific process improvements included optimising reagent dosage and concentration in the floatation circuit and air flow rate modifications, resulting in increased copper liberation in the grinding circuit."

It would be a very strange process plant if optimising reagent dosage and other modifications in the floatation circuit resulted in increased copper liberation in the grinding circuit...
