Traditional identification of ore minerals with reflected light microscopy relies heavily on the experience of the observer. Qualified observers have become a rarity, as ore microscopy is often neglected in today’s university training, but since it

Anew system has been developed to improve the interlaboratory accuracy in maceral and reflectance analysis of single seam bituminous coals. It performs automatically both types of analysis, following the same steps as the manual method. Scanning, foc
