In this study, the breakage properties of nine different chromite minerals, originated from the Kayseri region (Turkey), are investigated at batch grinding conditions based on a kinetic model. For this purpose, firstly, samples taken from nine different mines have examined mineralogical by using thin and polish sections then these sections have been investigated texture of chromite mineral and gangue mineral. Secondly, Standard Bond's grindability tests were made for nine samples. Thirdly, experiments were carried out with five different mono-size between 2.8 mm and 0.075 mm formed by a 2 sieve series fraction. Then, parameters of Si and Bij equations were determined from the size distributions at different grinding times, and the model parameters were compared for nine different chromite samples, and the relationship between the Bond's grindability (Gbg) and chromite grade with breakage parameters (Si, aT, γ and φj) were examined. The validity of the obtained relationship parameters of aT and φj has been confirmed with correlation, through a regression analysis of samples of chromite. © (2007) by the Chamber of Mining Engineers of Turkey All rights reserved.
