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.
Cementation removal of copper from solutions obtained during pressure leaching of sulfide zinc concentrates using the rotating disc method is investigated. The negative action of lignosulfonates of the process rate is shown, its kinetic parameters are determined, and assumptions on possible causes of lowering the cementation rate are expressed.
