(Photo: UBC) The recent COP26 event in Glasgow, U.K., reiterated the criticality of base metals in the green-energy transition. Copper is classed as a high-impact, high-intensity metal.
When stainless steel grinding media was used, the copper flotation recovery was very high (>90 % in the rougher stage) without the addition of NaHS, so its use was not warranted. The flotation of the bornite was not reduced by oxidation, in fact copper mineral recovery was the highest under the most oxidising grinding conditions.
