An ore body of spodumene (LIAI(SiO3)2, a common form of the critical metal lithium) is approximately 18% by mass spodumene with the rest quartz (for the purposes of the assignment assume only these two minerals present). Processing of this ore body involves a number of steps: A. Wet grinding to reduce the particle size from a P80 of 2.2 cm to the P80 of 90 μm required for froth flotation. B. Froth flotation to separate the spodumene (valuable) from the quartz (gangue). C. The valuable spodumene is sent for further processing and on-selling. D. The gangue quartz is sent to a thickener for dewatering and recycling of the water.
