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.
Lithium recovery from lepidolite was studied experimentally, and a sulfuric acid procedure for lithium recovery was suggested. It ensures the maximal degree of lithium recovery from this mineral at minimal power consumption. The suggested procedure creates prerequisites for large-scale involvement of lepidolite into lithium metallurgy, taking into account large amount of developed lepidolite deposits and steadily growing demand for lithium products.
