Closed circuit crushing is advisable in larger tonnage operations for maximum grinding efficiency and capacity. Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements.

the most quartz-rich feldspar separate the abundance of quartz reaches Q~40%, and is proportional to grain-size : up to 80% (100-160 pm), it decreases to Q 40% in the range 70-IOOprn, and to'L1OX in the smallest fraction (40-70 pm). This effect is probably due to …
