Transformation of grains of technological raw materials in the process of obtaining fine powders

Crushing and grinding of materials are the most common processes sample preparation for subsequent analysis industrial application. Recently, has become one popular methods producing nano-sized powders. This study investigates certain features grain transformation in process ores with finely dispersed valuable components order to liberate them, as well specifics metallurgical raw materials, metals their mixtures using them initial other technological processes. We identified examined structural morphological changes various powders after ultrafine scanning electron microscopy X-ray microanalysis. It was proved that take into account artifacts during analytic studies solid samples development processes, fine heterogeneous especially if they contain metals, requires monitoring ground product by
