Absztrakt

The energy consumed in the process of comminution highly depends on the mechanical properties of the materials being ground, which is controlled by the constituent minerals, their relative abundance and the texture. The quantitative description of textural information is essential in determining which textural characteristics can be attributed to certain mineral processing behaviours. The researcher’s opinions on the effect of different textural elements on the grindability differ. A correlation which can attribute numerical crushability and grindability values to certain textural features have not been established yet, however some general conclusions can be drawn. The effect of the mineralogical constitution is negligible, but the variation in hardness and the texture has a great impact.
