Analytical data

Result	ORIGINAL ORE CONTAINS 50-80% QUARTZ AND 20-40% KAOLINITE ON AVERAGE, ALTHOUGH IN SOME <180 MESH ORE SAMPLES KAOLINITE INCREASES TO 60-67%, QUARTZ IS REDUCED TO 27%, AL2O3 CONTENT IS 27.2%. IN THE <320 FRACTION QUARTZ CONTENT DECREASES TO 7-8% AND AL2O3 IS 30% AND IN SAMPLES OF <2 MICRONS THE QUARTZ CONTENT MAY FALL TO LESS THAN 1% WHILE AL2O3 IS 38%. THE KAOLINITE FORMS PSEUDOHEXAGONAL FLAKY CRYSTALS WITH GRAINS OF AGGREGATE USUALLY LESS THAN 2 MICRONS.
