Özet

Morphological properties of barite particles ground by autogenous and ball milling were examined by three-dimensional methods, namely, Brunauer-Emmett-Teller (BET) nitrogen adsorption and Permaran methods in terms of surface roughness and acuteness, respectively. The experimental study showed that autogenously ground products have lower roughness and acuteness. On the other hand, Hallimond tube flotation tests were performed to evaluate the floatability of those particles ground in different environments. Morphological measurements and flotation tests revealed that particles with smooth surfaces gave better floatability. (C) 2004 Elsevier B.V. All rights reserved.
