flotation process in mining

Froth Flotation Process

This new process, flotation, whose basic principles were not understood in the early days, was given to metallurgists and mill men to operate. Flotation research was done by 'cut and try' and empirical methods. The mining industry had no well equipped research laboratories manned by scientific teams.
