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

The paper considers issues of mechanical activation of phosphate fines, low-grade by its chemical composition and off-grade by its grain fineness mineral raw material. Results of the research showed that increase in the content of soluble form of P 2 O 5 is more than in three times, from 17.61 to 53.15%. Specific surface of the activated phosphate fines increases from 0.25 to 0.86 m 2 /g. The activation increases degree of dispersion and changes morphology of the phosphate fines disperse particles.
