| description | The research results of the effect of grain-size distribution of the starting sample of size class -3.35 mm on the value of the Bond work index OF grindability, obtained by the method of shortened procedure by prof. N. Magdalinović, clearly indicate that the characteristics of starting sample significantly affects the value of resistance to comminution. Differences in values of the Bond work index of grindability for low-grade copper ore of 5.4 kWh/t or about 42 % and high-grade copper ore of 3.77 kWh/t or about 35%, from the point of the theory of comminution and practical application in designing and selection of process equipment are of particular importance. |
