3D modeling for mineral resource assessment of fluorite ore
Flotation used in plant processing is the most efficient method to extract fluorite from the other elements. Due to high quantity of the fluorite resource (~ 5 Mt), an average grade of 28.0% CaF 2, planned production of 150,000 t/year with an open pit, the life span of the mine is estimated to be over 10 years.
