Fluctuations in the popularity and usage of flotation

Flotation columns installed in the 1960s were overwhelmingly in base metals, with 45% in lead, 25% in zinc operations and 20% in copper operations. The remaining 10% of flotation columns were installed in coal. During the 1970s there was a major transition away from column flotation use in both zinc and lead, and a minor increase in use in
