Flotation tailings, resulting in obtaining copper concentrate for further pyrometallurgical processing, usually stored in a tailings lake. The tailings still …


Flotation tailings are hazardous due to physical and chemical instability and are currently considered one of the main pollution concerns of mining industry. Most of these tailings are fine-grained residues with low copper content (0.1-0.8%) and include toxic compounds, such as heavy metals, arsenic, and flotation reagents, among others.


The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steady-state. The analytical profile of the entire flotation circuit is: -The rougher flotation feed; Question: A froth flotation process is used to concentrate copper ore. It is a two-stage process that involves one rougher stage ...
