Processing Iron Ore In Flotation Cells
Flotation Cells
The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation …

General Process of Copper Sulfide Ore Flotation
This process is more advantageous for copper-sulfur ores where the raw ore contains low sulfur, and the copper minerals easily float. Copper and sulfur minerals are first mixed and floated in a weakly alkaline slurry. The mixed concentrate is added with lime to separate copper and sulfur in a highly alkaline slurry. 3.
