The mineral content can double in a matter of minutes, changing the flow characteristics dramatically. The processes are complex, with many circulating loads. The operator not only has to think of what is coming, but also what is coming back. Grinding typically has two recirculating streams and flotation can have as many as 10.

Among these approaches, flotation is known as a more effective and economic way to harvest microalgae by taking advantage of their natural characteristics of relatively low density and self-float [ 7 ]. For flotation success, generally, the bubbles are negatively charged with large size and hydrophobic (HPO) surface.

Obtaining the greatest possible densities of spores is an advantage in inoculant production because the inoculation can be made with less material, while maintaining the same number of spores (Feldmann et al. 2009 ). Sporulation increased in absolute numbers, as time went by, but the differences were not statistically significant (Table 1 ).
