It was revealed that Guyana bauxite shows excellent alumina extraction. However, due to its specific composition – shell like coarse crystals of kaolinite, secondary gibbsite, low iron-bearing minerals and high kaolinite content – under-recovery of alumina, desilication and thickening problems, and high soda consumption are possible issues.
