The earlier versions of OXFLOAT CTC3 had been in production since 1972 and currently Oxflo’s manufacturing partner supplies 700 mt of this product to their local market annually. They have a further manufacturing capacity of 800 mt, taking them to a total of 1500 mt per year. Currently OXFLOAT CTC3 has displaced AM2 at one … Read more

Hydroxamate Collectors

float oxide copper

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
