In the cost analysis for the comparative period 1 st quarter 2018 and 1 st quarter 2019, an increase in the cash costs from 136.1 US$/lb (61.7 US$/kg) to 138.0 US$/lb (62.6 US$/kg) was calculated. The cost increase of 1.9 US$/lb (0.9 US$/kg) only accounts for an increase of 1.4 %, crucial, however, is the make-up of the costs (Table 2).

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

Conditioning and concentration of microalgae are accomplished by the process steps of grinding a dilute aqueous dispersion of microalgae in the presence of grinding media and then applying adsorptive bubble separation. This process is amenable to the use of dilute feed microalgal dispersions such as are encountered in the production of algal biomass for biofuel applications.
