Maximise pyrite depression in copper ore flotation using …
In fresh water, the oxidation of pyrite at alkaline pH inhibits the copper activation on pyrite surfaces and the depression of pyrite in copper ore flotation is normally not a problem (Li et al., 2012). However, saline water facilitates pyrite activation by copper ions and therefore increases pyrite recovery in copper flotation (Mu and Peng ...

A New Collector for Effectively Increasing Recovery in Copper Oxide Ore
A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and …
Parametric Optimization in Rougher Flotation …
The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, …

Copper oxide ore is characterized by low ore grade, fine embedded particle size and severe slime coating, which is a difficult ore to be processed in China [1]. Malachite [Cu 2 (OH) 2 CO 3] is a classic type of copper oxide and can be widely applied in copper metal extraction [2].
Froth Flotation
Froth flotation is a selective separation process to separate valuable materials (recyclables, minerals, and other fine-size waste) from unwanted materials (gangue) using air bubbles in a general floatation tank, Jameson flotation cell, or flotation column.
