Froth Flotation and Gold Extraction - Manhattan Gold & Silver

Jul 23, 2014· Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold's hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual ...

Lower-pH Copper Flotation Reagent System | Department of ...

It flocculates fine material and may occlude fine copper-sulfide particles. Lime increases the viscosity of the mineral slurry and tends to hinder aeration, slowing flotation kinetics. In addition, the calcium ion also has been shown to decrease recoveries of lead and molybdenum-sulfides and to reduce the recovery of free gold.
