Mining Techniques and Economics

The sawing process of granite samples from thirty-eight kinds of rocks by a diamond multi-wire saw in an ornamental rock processing plant in the city of Nova Venécia, Brazil was studied using data collected in situ. It was proven that the ratio between the total volume of stone processed and processing time has a strong relationship, a Spearman coefficient absolute value higher than 0.55, with energy consumption and hardness. Thus, it is possible to include energy consumption, hardness and time in a single coefficient. Samples with higher, lower and average values for the proposed coefficient were studied by X-ray diffraction and quartz content was found to be directly related to both the proposed coefficient and hardness.
