I wanted to gauge estimated amount of ilmenite that can be extracted from Lunar regolith. From that, ultimately I want to derive the amount of oxygen that can be extracted out of it. Any estimate or references will be helpful.

Ilmenite occurs in abundances as high as 25 wt% in some lunar basalts. Maximum yields calculated as mass of oxygen per mass of rock thus range from 2-2.5 wt%.
