2.. Barite flotationBarite pre-flotation is performed in two concentrators Bunge/Araxá and Ultrafértil/Catalão. Microflotation studies by Albuquerque (1995) indicated that pure corn starch depresses more effectively fine barite (−43 μm) than coarse barite (+43 μm). Barite pre-flotation of natural fines (fines produced after rod milling) was …
