Handbook of Flotation Reagents | ScienceDirect
The sequential copper–lead–zinc flotation practice utilizes several major reagent combinations in sequential copper–lead flotation, which include: bisulfide method, starch/lime method and soda ash/SO 2 or lime/SO 2 method. The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of zinc is the most common practice in the treatment of …
Lower-pH Copper Flotation Reagent System | Department of ...
A new reagent system, developed by Versitech, Inc., with assistance from DOEs Inventions and Innovation Program, recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite. The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide.

Flotation Reagent - an overview | ScienceDirect Topics
Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).
