The Eriez HydroFloat has a long track record in potash and phosphate operations for coarse particle flotation, but, according to Eriez, it is well suited to metal recovery as well and, when added to the end of the flotation process, can improve copper recovery by four to six per cent.

For a long time, “go big or go home” was the name of the game in flotation. Since the early 1900s, flotation has traditionally progressed by making flotation tanks increasingly larger to process more and more ore.
