FREEZING METHOD IN MINERALOGICAL STUDIES

To solve the problems of possible extraction of rare, trace elements from coals or ash dumps, samples of sulfides were taken from coal mines of the Donetsk coal basin and frozen, as a result of which the surface of the sample was covered with a significant amount of minerals such as arsenosalts, copyapites, zeolites and their varieties, which are much easier to explore. The freezing method can be used for stage analysis. A qualitative pattern has been established - the higher the degree of coalification of coals, the less the yield of zeolites, arsenosalts, copiapites and similar minerals to the surface.
