The proof of lower power-consumption is that the 10 cells of the National Copper Co. were run with a 30-hp. motor and treated 500 tons per day; the same tonnage treated by a propeller machine would have taken close on to 100 hp. This figure has also been confirmed at other places. The power required will vary from 2 to 3 kw.-hours per ton.

Flotation Machine. Conventional flotation machines house two functions in a single vessel: an intense mixing region where bubble–particle collision and attachment occurs, and a quiescent region where the bubble–particle aggregates separate from the slurry. ... For example, a 95% recovery of copper in the feed ore might give a concentrate ...
