Copper Oxide Flotation - Mineral Processing & …
Continuing with the evaluation of copper oxide flotation using hydroxamate we now evaluate a rock that’s 41% copper oxide with some lead oxide included. Sample B: 1.8% Copper about 41% Oxide Cu. Rougher Tests: Unseen in these charts is the order in which the results were obtained. The last/best “Blue” dot (the best data point) was the last test of the series.

oxidized ores was patented in 1905 (Schwarz, 1905) and has since been developed and adapted as the preferred pretreatment method prior to the flotation of oxide and mixed copper ores containing both oxides and sulphides. The reagents used in this technique of activating base metal oxides are alkali sulphides (Soto and Laskowski, 1973) such
AN INVESTIGATION OF COPPER RECOVERY FROM A SULPHIDE …
Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged. The flotation of a natural porphyry copper ore with bornite and ...
