Session three – Flotation Circuit Operation

In recent years the mineral processing industry has downsized its labor force, installed new technology with larger equipment and incorporated plant wide automation, all in an effort to improve productivity and performance while maintaining operating cost at a minimum. As a consequence of these actions the operator is now required to make more and better informed decisions. To meet the educational needs at the concentrator operation level, the facilitator has developed a Flotation Circuit unit operations Program

A partial list of topics covered in this session include:

• Mechanical Flotation Cells,
• Column Flotation Cells,
