Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Effect of the concentration of sulfuric acid used for beryl sulfatization, degree of beryl grinding, temperature and duration of beryl sulfatization, and other technological parameters of sulfuric acid decomposition on the extent of beryl recovery was studied. The results obtained made it possible to suggest a method for preparation of beryl concentrates for sulfatization. The method is based on a mechanochemical activation of this kind of raw materials and can serve as an alternative to the conventionally employed beryl activation techniques.
