At this stage, the mineral is mixed with water and wet milled to an optimal granulometry to achieve flotation. The flotation process yields two products, a concentrate and tail streams, that are sent to dewatering systems for water recovery. These systems usually include thickeners, hydrocyclones, and filters.

The following optimization goals were set along with supporting considerations; (a) Microalgae at harvest often has pH between 6 and 8. Thus, the goal for pH optimization was set to range between the pH values 6–8, to avoid the anticipated additional process costs associated with pH adjustment during dewatering. (b)
