In a typical feldspar operation extraction and size reduction may account for 20 to 25% of operating costs. Production of feldspar from feldspathic quarry fines and / or mine tailings would avoid this cost as the material has already been extracted and crushed. Other benefits arise from a reduction in waste treatment and disposal, an increase ...

Feldspar extraction, however, dominated the quarry ventures. Production grew slowly but steadily between 1880 and 1960, after which it declined. Presently the pegmatite is excavated, ground, and its minerals are separated by a y floatation system. The leftover quartz grains provide an ideal beach sand and can also be used to produce glass.
