The photos above (Figure 3.16) show examples of different mineral habits. Habit, a property closely related to crystal shape, includes shape and size of crystal faces, how forms combine, how well developed different forms are, and the way multiple crystals grow together.Habit, thus, is the characteristic appearance a mineral can have.

Classification helps to improve the throughput capacity of the processing circuits and also enhances the efficiency of downstream equipment. Air classifiers are broadly categorized into static and dynamic units. In static air classifiers, particles are classified by the air flow along its direction (Knoflicek et al., 2004). Over time, the ...

11. HYDRO CYCLONE CLASSIFIER Hydro-cyclones are used by in mining industry to separate minerals based on size and density. Slurry is given a vigorous rotation in the cyclone which generates a radial force field. Large/dense particles are driven to the outer regions and underflow, while small and light particles are attracted to the core and …

Chemistry and crystal structure (and crystal habit) together define a mineral. The task of classification can range from being simple to complex. In some cases, knowledge of some properties may be sufficient for complete identification. In other cases, classification of a mineral may require more complex chemical or X-ray diffraction analyses.
