Abstract

In this study, the relationships between the liberation degree and the kinetic breakage parameters of a chromite ore obtained from the Burdur (Türkiye) were examined under the laboratory conditions. Firstly, liberation degrees for chromite particles were determined by the particle counting method in a metal microscope for 4 different size groups. Secondly, the breakage parameter of chromite ore which was dry ground with a ball mill was obtained using standard test methods. Additionally, the model parameters were also determined for the fractional interstitial fillings (U) of the chromite sample. Thirdly, the kinetic grinding parameters were compared with the liberation degree of the chromite sample. As a result of the tests, a very good correlation was obtained with R2=0.998, and regression analysis in the grinding processing of the chromite ore was used to verify the validity of the relationship parameter of Si that was produced. To these, it was found that interstitial fillings (U=0.6, 0.8, 1.0, and 1.2) have an effect on the grinding.

含间隙充填物的动力学磨矿参数与铬铁矿释放度的关系

在实验室条件下，研究了从布尔杜尔(trkiye)中获得的铬铁矿的解离度与动力学破碎参数之间的关系。首先，在金属显微镜下用颗粒计数法测定了4个不同粒径组的铬铁矿颗粒的解离度。其次，采用标准试验方法获得了球磨机干磨铬铁矿破碎参数。此外，还确定了铬铁矿样品的分数间隙填充量(U)的模型参数。再将动力学磨矿参数与铬铁矿样品的解离度进行比较。试验结果表明，两者具有很好的相关性，R2=0.998，并通过对该铬铁矿磨矿过程的回归分析，验证了所得Si关系参数的有效性。结果表明:U=0.6、0.8、1.0和1.2的间隙充填对磨削有一定的影响。
