A New Collector for Effectively Increasing Recovery in Copper Oxide Ore
2013. The use of mixtures of collectors has long been recognised in plant practice and has been shown to enhance flotation performance. These benefits have been reported for a wide range of collector mixtures (anionic, cationic and non-ionic) and include lower dosage requirements, improved selectivity and rates and extents of recovery and an increase in the recovery of …

Assessing the depression of high-concentration pyrite in copper …
Pyrite (FeS 2) is known as a major sulphide mineral in base metal ore deposits.It is depressed in copper flotation unless precious elements such as gold (Au) and silver (Ag) are associated with it. The depression of pyrite has been a challenge in copper flotation as pyrite can be activated by copper ions produced from copper sulphide oxidation.
