· A quick analysis discussed below shows that roughly 60–80% of the total 25-year cycle costs for a large flotation machine are spent on energy while the initial investment comprises less than 10%. As a result, if a small saving in investment is achieved by compromising energy efficiency, it can quickly turn into big losses in operational costs.
