Application of magnetic separation for modifying the composition of basalt raw materials

Аннотация

The results of studying the process of modifying the composition of basalt raw materials using the magnetic separation method are reported based on the example of basalt of the Myangdukha deposit (Arkhangelsk oblast). The chemical and phase compositions of magnetically enriched and magnetically depleted fractions have been determined by mass spectrometry and X-ray powder diffraction. The process of sintering these fractions has been studied by the DSC/TG method. The phase composition of sintering products has been studied and some of the physicochemical properties of the obtained samples have been determined.
