Induced-air flotation cells deliver airflow into the pulp with the turning of the rotor, which pulls in the ambient air. No forced-air supply system is required, eliminating the capital and operating costs of blowers and distribution piping. Airflow compensation for varying feed densities is automatic, minimising the need for operator attention.
Nov 04, 2016· Low grades, complex ores and rising energy costs have prompted the development of entirely new flotation vessels, improvements to existing technology, and new thinking about flotation flowsheets.
