rhsurfer, from previous announcements 6000 micron flakes only mentioned for north east balama. Most people have no idea why flake size is important anyway. Flakes for lithium ion batteries are between 5 and 70 micron with the smaller the better but its harder to make high purity spherical graphite from natural small flake graphite so they start with larger flake which is usually liberated in purer form and treat it to make smaller flake. However, for graphite <80 micron, the energy and time required to make very small flake is exponentially greater than for >100 micron flakes. The benefits of increasing flake size fall rapidly. Also the more energy and time required to make very small flakes the more the contamination from machine wear which is a real problem. Very large flake has current uses in graphene manufacture which is niche only and it will a decade or more before large volumes of natural graphite are dedicated to graphene. The current sell off speaks volumes about the average punters knowledge
