How Froth Flotation Works
To be successful in the recovery process, several of these cells placed one after another will be required to provide the necessary flotation time required to recover the amount of mineral present. There are several different cell designs, each one a little different, depending on the job that they are doing.

60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
