Titanium Corp would fit after the NRU, where the NRU tailings would be further treated to remove residual bitumen, then the minerals classified into various fractions. Zircon was on mineral they interest in.

The flow quality is evaluated using conventional equation as, where and are the mass flow rates of gas and liquid phase, respectively. This definition holds true for both one component two phase flow and two component two phase flow, provided adiabatic boundary condition is maintained.
The void fraction can be used in calculating two phase mixture specific volume and in conjunction with fanning friction factor to predict two phase frictional pressure drop but is found to be limited to certain flow patterns. It should be note that it’s not only the specific volume but also the dynamic viscosity that is required to be calculated based on the void fraction to be able to use in conjunction with fanning friction factor and finally to calculate frictional pressure drop. The fanning friction factor calculated in terms of two phase specific volume and two phase dynamic viscosity is often referred to as two phase fanning friction factor. The pressure drop models of Ciccihitti et al. (1960) and that of the Shannak (2009) are based on the similar concept but use flow quality instead of void fraction in calculation of two phase mixture physical properties.
In addition to frictional pressure drop, void fraction plays a key role in calculation of two phase hydrostatic pressure drop . The hydrostatic component is most sensitive to void fraction and requires accurate estimation of void fraction.

this is good information, i would like to know what inferences will consider during blast resistant building

thanks & Regards
