CopperCobalt ores Danafloat
CopperCobalt ores. The tails produced in the first differential flotation step is followed by a pyrite and pyrrhotite flotation stage using xanthate and MBT, leaving the cobalt minerals in the flotation cell tails. The cobalt minerals are then floated by using sulphuric acid to decrease the pulp pH to 4. Sodium sulphide is conditioned in the pulp.

Copper Ore Types: Sulfides vs. Oxides | INN
Copper ore types: Oxides. The copper sulfate solution (called the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SXEW) process. Alternatively, the copper can be precipitated out of the pregnant leach solution through a process called cementation, whereby the copper is contacted with scrap iron.

Copper processing Ores |
In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in the orewater mixture, or slurry. The reagents provide an attraction between the surface of the copper minerals and the air bubbles.

Flotation Froth an overview | ScienceDirect Topics
Froth flotation relies on differences in the surface chemistry of the ore and waste grains. Sulfide ores in particular are more readily wet with oil than water. Grains of clay, sand, and other seabed detritus have the reverse tendency. Typically something like pine oil might be used to wet the mineral grains.

Improve Copper Yield in Flotation Tanks Emerson
Rich copper concentrate is produced from crude copper sulfide ore by means of a flotation process that takes advantage of the physical and chemical properties of small copper ore particles. To maximize the yield of copper, pH control is necessary in the flotation tanks. Crushed ore (containing 1 to 2 % copper), along with water and a lime slurry, is fed into a ball mill.
