Description of key information

Zirconium iron pink zircon: MMAD1=4.99µm, P1=0.46 ; MMAD2=10.25µm, P2=0.54; GSD1=1.37, GSD2=5.80
Zirconium iron pink zircon: D50 = 2.5 µm

Additional information

Total Dustiness (airborne fraction): 13.30mg/g (experimental results, DMT Report)

Mass median aerodynamic diamater of airborne fraction: MMAD1=4.99µm, P1=0.46 ; MMAD2=10.25µm, P2=0.54 (distribution fitted to cascade impactor data). Geometric standard deviation of MMAD1: GSD1=1.37, of MMAD2: GSD2=5.80

Fractional deposition in human respiratory tract (MPPD model, based on calculated MMAD):

Head (ET): 66.7%

Tracheobronchial (TB): 2.0%

Pulmonary (PU): 5.9%

Particle size analysis by laser diffraction:

d50 = 2.5 µm

d90 = 4.7 µm

d10 = 1.3 µm

(All values were calculated assuming that the particles are spherical)
