Copper Oxide Flotation

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) … Read more

Hydroxamate Collectors

Let me point you to two good papers on the flotation of mixed copper oxide and sulphide minerals with xanthate and hydroxamate collectors. A great detailed thesis called “An Investigation of Copper Recovery from a Sulphide-Oxide Ore with a Mixed Collector System” and one called “Flotation of mixed copper oxide and sulphide minerals with xanthate and … Read more
