High-performance reagent modes for flotation recovery of platiniferous copper and nickel sulfides from hard-to-beneficiate ores View the table of contents for this issue, or go to the journal,Flotation performance, structure–activity relationship and,,1. Introduction. Copper is an extremely useful industrial metal and at present, the most important source of copper is the copper sulfide ores , , , , .The copper grade in nature copper sulfide ores is low, and froth flotation has been widely applied to separate copper sulfides from its gangues to obtain high-grade copper concentrate for further processing , .Lower-pH Copper Flotation Reagent System | Department of,,A new reagent system, developed by Versitech, Inc., with assistance from DOE's 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.
