Maybe it doesn’t get all the way there and you lose a little bit of gold, but that’s a result to a degree of recovery, whereas in a flotation cell, this is going to be very binary. I mean, if this thing sinks, you recover zero of it as opposed in a cyanidation plant where maybe you’ve recovered 50% or 70% of the particle before it moves ...

Jan 01, 2016 Application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals, followed by the installation of pyrite flotation plants on numerous gold mines in South Africa.
