Hope this helps with your education Spid81. Less heat and pressure means a softer material to process which is one of the reasons Lindi will retain graphite flake size. The fact that schist is foliated and arranged in layers means most of Lindi’s graphite will be easily liberated through minimal grinding and heavy floatation. The two exact qualities you need when your mine is based around large flake retention. It’s not hard to work out why Lindi’s graphite mine has the highest percentage of jumbo and super jumbo flakes when compared to its peers. Luck only starts with discovery Spid. The experts then take over and build the mine.
